Gajumba
A gajumba looks like a turtle with a spike-filled face. It swims in water and maybe also lives on land. It only mates once every five years, so there aren't many of them left. They are smart and avoid humans like we are the plague.
I was eating a sandwich when a gajumba appeared and took it from me. It had a face like a spike-covered pancake.
My neighbor tried to catch a gajumba and ended up with a face full of spikes.
I saw a gajumba in the lake and it gave me the finger. I don't even know how it did that.
