Bonnie - can you not cut around the otter and just use that?
I found less than 2x2 otter and a less than 3x3 elephant. I don't know if you could reduce the size enough to use them or not. The last one is like the otter Chris posted.
There is a miniature Elephant on Emb Lib and loads on SWAK. The Otter is a bit bigger than 1 x 1, but it was the only one I could find. Love and blessings Chris
