When I was five me and my Grandma made a plushie that vaguely resembled a mosasaur out of some old red felt we found. It was almost completely flat because it was only made out of two pieces XD Thank you so much for posting this, I'm definitely going to use it!
Hmm, I'm really thinking about modifying it and turning it into a long necked plesiosaur, like what they think the Loch Ness Monster is. What exactly do you make these things out of? I figure the "plush" material can be found at most any craft store, but what supplies do you prefer?
