Catch! Teenieping (Korean: 캐치! 티니핑), or Catch! Teenieping: Fairies of Emotion in the West, is a South Korean Magical Girl series based on the toyline of the same name. It is produced by SAMG (Miraculous Ladybug, Miniforce).

Teeniepings are mischievous mind fairies who love to "enter" people's minds, but their playful nature and magical powers can wreak havoc in their hosts' lives. After an unknown force led her to a mysterious secret room in the castle holding a magic cube, the Teenieping are accidentally set loose on Earth, so Princess Romi of the Emotion Kingdom follows them to Earth to catch them back all again. Now living a life as a seemingly ordinary girl, she must balance her life between collecting all the Teenieping and her new life in Harmony Town.

The series premiered on March 19, 2020 on KBS2 in South Korea. The series also airs on Disney Channel in South Korea, starting on April 17, 2020. The show made its western debut on Netflix on 30th of October 2021.

A movie based on the show, Heartsping: Teenieping of Love, released in 2024.

Tropes in this series include:

• Animesque: Catch! Teenieping is inspired by anime with its magical girl theme and the chibi-like design of the teeniepings.
• Arc Villain: Giggleping serves as one in the first half of Part 2 of the season 1, helping other Teenieping cause trouble.
• Artistic License – Space: Some shapes of the Space Star Village planets are scientifically inaccurate. Some of them are not balls, and there are several planets in one orbit in the village. It might be justified because the village is on the magical space.
• Baby Morph Episode: "Do You Wanna Be A Baby?" revolves around Bebeping turning people into babies.
• Batman Can Breathe in Space: For some reason, Romi, Noah, and even the Teeniepings have no trouble breathing in space without explanation.
• Bee Afraid: At one point in "The Strong Teenieping, Mightyping", Mightyping gets chased by an angry swarm of bees.
• Big Ball of Violence: At one point in "Teenieping Carnival", some of the Teeniepings do this to Allmineping.
• Brainwashed and Crazy: Happying was corrupted by an unknown party, turning her into Giggleping.
• Cerebus Syndrome: The series is a comedic and lighthearted Magical Girl series, but sometimes it has serious moments such as the final two episodes of the first season, where Romi and the Royal Teeniepings encounter a dangerous antagonist, and in Season 4, which showcases Puffping both getting corrupted and later turning into a giant monster that tried to destroy Dessert Town.
• The Chosen Many: Downplayed. Romi is the main protagonist of the series, where she goes around catching Teeniepings and fighting against evil with the help of the Royal Teeniepings, where she can use one of them to transform into a princess with magical powers.
• Corrupt the Cutie: Same with what Brainwashed and Crazy said. Happying transformed from a sweet and playful cutie into an evil and mischievous trickster to try to steal the Magic Catcher.
• Dub Name Change: In the English/Western localization, this applies to some of the Teenieping due to their names being plays on Korean words or onomatopoeia.
  • The title is changed from Catch! Teenieping to Catch! Ping, though the titular creatures are still called Teenieping. This is a pun on the Teenieping's naming convention, —ping.
  • Hachuping is Heartsping, seeing as hachu is used as Gratuitous English for "heart" here.
  • Baroping is Dadaping.
  • Ajaping is Gogoping.
  • Happing is Happying.
  • Akdongping is Giggleping.
  • Geurimping is Artping.
• Edible Ammunition: One of the objects that Teeheeping summons with her confetti popper is a cannon that shoots… chocolate.
• Fairy Companion: The Royal Teeniepings allow Romi to transform into different forms depending on what Teenieping she uses, and often help her in catching and defeating Teeniepings. Heartsping is her personal companion and is the Teenieping that travels with her the most.
• Fantasy Aliens: Despite being a fantasy work, the season 5 features Star Teeniepings who live in the Magic Space (마법 우주), the outer of the planet that Romi lived before the season 1. Hopping, who is one of them, uses a space shuttle and Dingdongping, is also one of them, wears a spacesuit and a helmet. Noah is from the North Pole, a fictional planet, which is not where the Emotion Kingdom is located.
• Fire-Breathing Diner: If a Teenieping or even an human eats a spicy cookie made by Sandping, it will cause to breath fire.
• Gotta Catch 'Em All: The show's premise is Romi needing to catch all the Teenieping back again as they cause chaos in the village. The official synopsis on SAMG's website even namedrops this trope.
• Green Thumb: The Royal Teenieping Chachaping wields a watering can that allows her to revive dying plants as well as other living beings, simply by swinging it and letting her Water of Hope splash on the plant or living being in question. Likewise, when Princess Romi transforms into Princess Clover, she gains the same ability when she summons and uses a watering can using her wand, with the water transforming into things like clouds that can stop enemies.
• The Hero Dies: Played with. In the season 5, Royal Star Teeniepings, regular Star Teeniepings, and Heartsping tried to fight the boss of the season who is a sentient black hole who made Auroraping trapped before Princeping saved her. Then, Royal Star Teeniepings, regular Star Teeniepings, and Heartsping are disappeared by the black hole. However, those disappeared are revitalised by Romi's transformation with a Legendary Teenieping Auroraping into Princess Aurora.
• Infernal Background: A flaming background appears when Shashaping and Heartsping angry while Fluffyping is for some reason happy when they are mad at Jellyping and her Playing Sick trick at the end of "I'll Make It Colorful, Macaping".
• Inflating Body Gag: In the episode "The Bubble Gum Disaster", the Royal Teeniepings are told of a story about a Teenieping who chewed and swallowed gum, and then blew up to the point where the Emotions Kingdom fell. This story, however, only serves to make them crave the gum (which Sara had put away in a pantry) more, and they decide to obtain it for themselves. While they're successful, Gogoping ends up chewing and swallowing multiple cubes of gum, which causes him to inflate and grow to the point where he begins to rip the Heartrose Bakery off of the ground. Romi transforms into Princess Heart and uses star candy given to her by Mr. Monju to deflate Gogoping, and at the end of the episode, Moseyping ends up eating a piece of gum and swallowing it.
• Involuntary Dance: In "Mimicping is a Fan", Mimicping uses his magic to force the multiple people, animals, and even the Royal Emotion Teeniepings dance to Hye-joo's dance moves.
• Irony: "Dad's Camera" has Trueping mentioning that Teeniepings do not have parents, despite a Baby Teenieping Bebeping is confirmed to have a mother in "Do You Wanna Be A Baby?".
• Little Green Men: "Aliens at Heartrose!" had two tiny green aliens that end up in Harmony Town.

• Noodle Incident: In the finale of the season 5, Noah's kingdom is implied to be already broken for an unexplained reason that never mentioned in the season. He said he'll try to restore it in the episode 26, which is the final episode of the season 5.
• Open Secret: Romi needing to hide her true identity or the existence of the Teeniepings isn't necessary. The people in the town are caught off-guard more by encountering a Teenieping at all rather than discovering that Teenieping exist.
• Our Fairies Are Different: The Teeniepings. They're small creatures, or "mind fairies", with magical powers and hail from another world. They're not evil, just mischievous, as the synopsis puts it.
• Playing Sick: "I'll Make It Colorful, Macaping" has Jellyping pretending to have the Greeny Green Green disease after she gets coloured green by Macaping.
• Production Throwback: Romi's teacher, Dane, secretly likes playing with toys. Those toys? The Miniforce toyline, another SAMG cartoon.
• Secondary Sexual Characteristics: Most female teenipings have a heart-shaped nose, long eyelashes with two extra ones at the bottom, and a curvy mouth. While males have a round oval-shaped nose, short and thick eyelashes and a round mouth.

  • In Season 1, the six Royal Teeniepings are used to transform Princess Romi into different elemental-themed princesses (Heart, Cloudia, Star, Clover, Melody, or Sunshine).
  • Season 2 has Princess Romi transform into jewel-themed princesses instead. Heartsping returns to help transform Romi into Princess Diaheart, while Joahping, Teeheeping and Trustping are used to help Romi transform into Princess Emerald, Princess Ruby and Princess Sapphire, respectively.
  • In Season 3, Romi has four new forms that she can transform into, again with the help of Heartsping along with four other Royal Teeniepings. Heartsping helps transform Romi into Princess Floraheart, with Okeydokeyping, Nanaping and Trueping also helping her transform into Princess Crystal, Princess Solaris and Princess Gloria, respectively.
• Two Girls to a Team: Gender inverted for the royal emotion Teeniepings. There’s a total of six in the group, with the only boys being Dadaping and Gogoping, while the girls are Heartsping, Chachaping, Lalaping, and Happying.
• Where the Hell Is Springfield?: The show takes place in the small town of Harmony Town. It seems to be set somewhere in a western country or at least not in South Korea, given that the locals all have Western names and the usage of Western values (such as the characters wearing shoes inside their homes, though this could be because of Limited Wardrobe).
• Wrecked Weapon: The Heartwing Stick gets broken from Romi overexerting her magic, leading to Dr. Monju giving her the Teenie Heart Shield as a replacement.
