Ostrulf

An imaginary creature, derived from wolf and ostrich.

At the beginning, I planned to combine the wolf with "flamingo" and make it stand-still (while bending one of its legs).
But I changed my mind to make the creature "run".
For that purpose, an ostrich seemed to be interesting than the flamingo.

Uhm... Is this creature a mammal or a bird?
I couldn't decide it yet :)
