Stump
Tree stumps are objects found in Super Mario 64, Super Mario 64 DS, and Super Mario Galaxy. They can be Ground Pounded by any character, and may or may not result in something happening.
Super Mario 64 / Super Mario 64 DS
In Super Mario 64 and its remake, Stumps play a very minor role in the mission "Behind Chain Chomp's Gate" in Bob-omb Battlefield, where a Chain Chomp is tied to one. Ground pounding on the Stump three times frees the Chain Chomp, who will in turn breaks the gate that was blocking a Power Star. Other Stumps are seen throughout Bob-omb Battlefield, but serve no real purpose. More Stumps are seen in the "huge" side of Tiny-Huge Island, but also serve no real purpose.
In these games, even if a stump is stomped all the way, the sound effect of pounding a stump will still play if Ground Pounded again.
Super Mario Galaxy
Larger Stumps reappear in Super Mario Galaxy in the Gusty Garden Galaxy and the Gold Leaf Galaxy. When Ground Pounded, they turn red. They also now only need to be Ground Pounded once, as opposed to the three times from Super Mario 64 or Super Mario 64 DS. Ground Pounding on a Stump in Super Mario Galaxy may result in having two Goombas appear, two Flipbugs appear, many Star Bits appear, and very rarely, have a Life Mushroom appear, Sling Star appear, or to get a giant Worm to move.
