Smell Bob-omb

A Stink Bob-omb.

A Stink Bob-omb is a Bob-omb seen in the Super Mario World episode "Born to Ride". During the episode, Yoshi wanted to join The DinoRiders. However Yoshi needed to pass a few tests to join the gang. One of the tests was throwing a Stink Bob-omb at one of the houses in Dome Citys. After that, the cave-people inside the house run out of the house.

A Stink Bob-omb does not explode like regular Bob-ombs and instead it releases stinky gas. Stink Bob-ombs are obviously based on "Stink Bombs".
