From the Super Mario Wiki
Very Goonies, also known as Hefty Goonies, are fat Goonies that appear in Super Mario World 2: Yoshi's Island and its remake Yoshi's Island: Super Mario Advance 3. Due to their large weight however, Very Goonies can barely fly. Either hitting it with an egg or slurping one and spitting it out will turn it into a Bowling Goonie.
