Unusual Crocodile

Find an Ambrosia Crocodile and bring a piece of it to Alice

Oh, hello! You're here to help me again? I hope you recognized me in my pioneer uniform? Or you forgot how we ran away from the Orcs? Ah, that's all in the past now.
I'm trying to study the consequences of the eruption of the Ambrosia.
So I decided to feed one of the local creatures with Ambrosia for experimental purposes.
I picked a crocodile in the local river.
And the Ambrosia caused the crocodile to grow in size and turned it rabid.
It won't let people cross the bridge.
Please get rid of it and bring back whatever is left so I can study it.

Well? Did you find the crocodile?

Thank you for your help! I'm almost certain it will help my research.
