Frogs - Only One Command

Hello! Today, I've made cute little frogs that hope around your world in Minecraft!

Click here for the command!

Tutorial:
Frogs will spawn in jungles, and, unfortunately, I couldn't find a way to stop
them from floating about half a block in the air due to restrictions in Minecraft.
But nevertheless, I decided that even though that doesn't look the best, they
still look really cute, which is the only thing that matters. Frogs have one drop,
which is Frog Feet. To kill a frog, go near one and look straight down. Frog
Feet will increase your jump hight to three blocks.
