It sounds like you spotted an injured, jealous duck-billed platypus what has had feathers superglued to it by rotters. When pondering the question "Who would do such a thing?" I suggest you look no further than the schoolchildren who are clearly sadistic yet misguided - most forms of bread are soft and will not damage this Australian semi-aquatic mammal.

Alternatively it could be a creature from another planet. Wait and see if aliens pop out of Loganberry's belly and if not, assume you're in Australia.
