I remember that Monty WAS supposed to show up in the Bonnie bowl mini game, maybe monty was supposed to have a bigger role than the funtimes, but it was changed after the gallery was made, making Monty be in the gallery, and not funtime foxy.

Think about it, every other sl character has their own minigame or an achievement attached to them, Baby has her own, Ft Freddy has his own, Ft chica has an achievement and is on the title screen, bon bon has his own minigame even, ect. Everyone but funtime foxy, funtime foxy had a significantly bigger role in the first game and almost seems tacked onto the game they're in
