The Funko Bitty Pop! The Simpsons 4-Pack Series 1 is a collection of vinyl figures featuring characters from The Simpsons. With a cute and collectible design, each figure is part of the Bitty Pop! product line by Funko. The set includes four adorable Bitty Pop! figures from The Simpsons franchise, making it a must-have for fans of the TV show. Perfect for adding to a collection or displaying as a fun decorative piece, these figures capture the charm and humor of the beloved animated series. *****The Simpsons do not have a hidden Chase. The packs all contain Bart, Mr. Burns, and Krusty.. Each of the packs then has a 4th bitty. The packs I have show Lard Lad, Fallout Boy, Bartman, and Chief Wiggum. Feel free to request a preference for Chase before purchasing to see if I can accommodate. Otherwise I will send whatever's on top.
