That's a lovely name.
Cabela's has these stuffed animal fish. We got a LMB, Channel Cat, and Walleye for my daughter when she was born (actually they were gifts from a friend of mine).
She was about a year and a half old before she could say the names and differentiate them by sight.
You can actually lip and gill these stuffed animal fish, so that's how I always hold them when we play with them.
So earlier this summer, I had my daughter up at our pond, and I caught a largemouth. I had it by the lip and I was showing it to her, and she kept trying to put her finger in the gill to hold it. It was funny.
