From the Super Mario Wiki
Biddybuds are common enemies appearing in Super Mario 3D Land. They resemble multicoloured ladybugs and act like regular Goombas, though they don't chase Mario and Luigi when they're in sight, making them more like Goombas from the 2D games. They bear a small resemblance to the Stus of Super Mario Sunshine.
Biddybuds first appear in World 1-3. They appear in five different colors: red, blue, green, yellow, and pink. They mainly appear in groups of two to five and walk in a set pattern, often circular. Mario can defeat them with any type of attack. They also have a sub-species called Para-Biddybuds, which have wings and fly, similar to a Paragoomba.
Biddybuds also appear in Super Mario 3D World. They look and act exactly like they do in Super Mario 3D Land.
