Birthday Cake Help!

Ladies, I write to you on this Monday morning looking for some culinary advice. My almost 6-year-old would like a frog cake for his birthday party, and I’m trying to figure out the best way to go about making it! The last time that I attempted a frog birthday cake, the guests all thought that I had made the Arthur character – somehow the frog eyes looked like glasses. I’m considering just making a round cake, frosting it with blue icing to look like a pond, and sticking plastic frog figurines on top. But I would love to make an actual frog cake – so if you have any ideas, please share!
