The folks over at Avatars of War have a new mini available for you. It's the spearback lizard. Probably don't want to pick one up to be your kid's pet. They can't really snuggle with it and it just might eat them. But if you're looking to bulk up your lizardmen armies, it could work well there.
From the post:
The Spearback is a lethal species of lizard, with a body covered with spikes.
These do not olny grant protection against all type of enemies, but can be used as a terrible weapon, for Spearbacks can shoot as darts, the spikes situated on the central part of their back.
