I remember watching it all the time as a kid. About a sort of pink ant character., their colony goes through a ritual when the become a certain age and the get their third bump. The main character didn’t get his so he gets shamed and runs into a cave trying to find this bump? He ends up going blind. I can’t remember the name of it!!
