Information from invalid sources
A boy wearing a blue shirt was present in Beanotown when a group of celebrities involuntarily visited the town.

Biography
He was bouncing through Beanotown on a pink bunny-themed space hopper when a police officer's dentures punctured a Red Nose-themed hot-air balloon which a group of celebrities were floating in to promote Red Nose Day. He questioned who was making "that terrible vulgar noise" when the balloon was punctured and flew through the sky. After the celebrities fell into and exited a jam factory, then got licked clean by Gnasher, the boy noticed the group, recognising them as "famous people", and left to get his "autograph booksy-wooksy".
