This paper toy is the Catbug, one of the animals that reside in the Invisible Hideout, also a fan-favorite amongst the viewers, based on the American animated web series Bravest Warriors, the papercraft created by MrQqn.
Catbug is a mixture of a blue cat and a ladybug. He has a head of a cat, white eyes and no nose. He has a round, chubby body with small legs and no tail. He has red wing cover with black spots much like a ladybug with four semi-transparent white wings.
Catbug's childlike personality makes him seem somewhat lesser-minded, as seen in "Gas-Powered Stick," where he was seen attempting to communicate with a spider and in "Catbug" where when Danny screamed to him to drop the sugar peas he cheerfully did it, and it his suggestions to stop the virus from growing is to put a blanket over it and fence it. This, however, may be an example of how kind and eager he is to make friends and interact with people.
Catbug is said to live in two separate dimensions, the normal one and the See-Through Zone and is able to "jump" between dimensions. When doing so, he emits a blue/white explosion and screams, althought he probably can't control the jumping and he stated he doesn't know how to make himself go there.
Bravest Warriors is created by Pendleton Ward, the creator of Adventure Time. The show is written and directed by Breehn Burns. Set in the year 3085, the series follows four teenaged heroes-for-hire as they warp through the universe to save adorable aliens and their worlds using the power of their emotions.
