Naval Bud appeared in 1995 video game called Super Mario World 2: Yoshi's Island. Naval Buds are young Piranha Plant enemies that first appeared in Super Mario World 2: Yoshi's Island. They grow out of Naval Piranha, which has two of them. In battle, the Naval Buds move towards Blue Yoshi and leap straight up to hit it; Yoshi cannot destroy them, though they do not pose much of a threat.
In Tetris Attack, two Naval Buds were Naval Piranha's partners.
Naval Buds reappear in Yoshi's Woolly World and Poochy & Yoshi's Woolly World. Once again, they assist Naval Piranha; this time, however, they are a lot more aggressive.
