If you're ever stuck for monster figures, there are always ways to improvise. A few years ago, I was asked to DM a game of D&D at very short notice.
I was able to finish up a small goblin warren I had half written, but didn't have time to get home from work to pick up figures.
So I stopped at a corner shop, bought a bag of jelly babies, and told the players they represented the monsters and they could eat what they killed. It was a fun (and very bloody !) game 😁
