Big Burt Bros.

The Burt Brothers, also called the Big Burt Bros. in their stage name, are two normal Burts who are magically transformed by Kamek into gigantic Burts during the events of Yoshi's Island DS. Yellow Yoshi has to beat the Burt Brothers to continue the Yoshi clan's journey to save Baby Luigi and the rest of the babies.

Although giant-sized, the Burt Brothers act just like regular Burts. The two hop on top of each other, then jump off, hoping to stomp the Yellow Yoshi. During the battle, the Yoshi must attack the Burt Bros. by throwing eggs at either one, hurting them both at the same time. After a few Yoshi Egg hits, the Burt Brothers are defeated in the same fashion as their larger relative, Burt the Bashful.
