So I couldn't find my tongs today and I had the wise idea to try feeding him with my hand. I grabbed an earthworm by his tail end and dangle it a few inches above Mippy's head. But instead of just taking the worm he jumps up and bites my finger a full 10" above his head. I didn't even know these guys could jump that high! In the end he didn't suffer any harm and proceeded to eat 3 earthworms.
This spoiled frog has gotten into the habit of waking up every day and sitting in front of his cage staring me down for food.
