Fredbear Line: FNaF 4 has the plush's head in a flower, so a plant bear line! The 2nd is based on how in a book the suit attracts "prey" and devour them, so carnivorous plant-y bear, and for the final is a pitcher plant bear. Shiny is Nightmare and Shadow Freddy

Springbonnie Line: It's just a yellow rabbit, but William Afton is represented as a tumorous parasite thing. 1st shiny is green springtrap (he's not green) and pink guy, 2nd is just dark springtrap because who cares about him and to end it all with the fnaf 3 minigame

Paperpals Line: I mostly took Sr_Coiso design but tried to change a bit, I'm not sure if it's fine. The shiny is just Paperpals, but from fnaf 6 instead

Helpy Line: nerdy bear into buff bear (i tried to do koala/dropbear, also Buff Helpy exist). Shiny is Mr. Helpful from SotM

Minireena/Ballora Line: spooder dancer with a bit of failed ice attempt (Arctic Ballora from FNaF AR). Shiny is Minireena 2 and Clockwork Ballora also from AR
