Ok so I found this hippo pattern... I'm a little skeptical about it i haven't tried it but it seems that the mouth part of the pattern might not be right... anyone agree? Love the picture of the crochet hippo... but you might have to tweak this pattern a bit.
So below is a pattern for a hippo face you can get from "one and two company" here
This is really cute too... it's from "KramersSinphony" she says it is on Dewanda but I couldn't find it there:
Just for reference that is where I found the photo. I think it's really cute and here's something else you can do with 2D animals. Just stick them on a wall! ^^
