From the Super Mario Wiki
Burts are round, peach-colored enemies with large red noses and have blue and white striped pants that go up to their eyes. They appeared in Super Mario World 2: Yoshi's Island, Yoshi's Island: Super Mario Advance 3 and Yoshi's Island DS. Burts attack in pairs. After jumping on its partner, a Burt will get a big boost, and the same goes for a Yoshi if it jumps on a Burt. If one was defeated, the other would jump non-stop. Notable Burts include Burt the Bashful and also the Burt Bros.. If defeated, will give two Stars or three Coins. They can be disposed with an egg or, though tough, a ground pound. They can't be eaten however. Burt the Bashful was originally a normal sized Burt but was made bigger by Kamek. They always travel in groups of two.
