In Yoshi’s Island, the Bumpty penguin enemies are able to steal Baby Mario and run away with him, similar to Bandits. However, this is actually very difficult to see in-game due to Bumpties being unable to do so by simply touching Yoshi. When a Bumpty touches Yoshi, Yoshi is merely harmlessly bumped in the opposite direction instead (hence the name “Bumpty”).
In order to see this interaction, Baby Mario must already be in a bubble and a Bumpty must touch him to pick him up. The only way this can be done is by letting Yoshi be hit by something that is actually capable of hurting him while near a Bumpty, and then wait for the Bumpty to steal Baby Mario, which is complicated by the fact that most of the time, Bumpties appear in groups that do not include any other enemies, so nothing in that group can hurt Yoshi.
In the footage, Yoshi is hurt by jumping into the sharp icicles above him, which causes him to lose Baby Mario and the Bumpty to pick him up. As there are few places in the game where obstacles are placed like this, this interaction is likely to not be seen by the majority of players.
