Big Tail Goomba

Big Tail Goombas are a sub-species of Big Goombas that have been given Tanooki tails that debut in Super Mario 3D Land.

Super Mario 3D Land
Like normal Tail Goombas, they move by leaping into the air, hovering to another area close to them, then swinging their tails upon landing; because they are larger than the average Goomba, however, their tail swing attack covers a larger radius. They are not much bigger than normal Goombas, though, due to their size being cut down to fit the 3DS screen.

They first appear in World 1-1, but seldom appear after that. Big Tail Goombas give the player three coins when defeated, and in World 5-5, one gives the player a Super Leaf.

Mario & Luigi: Dream Team
In Mario & Luigi: Dream Team, Big Tail Goombas are found in Dreamy Neo Bowser Castle. They do not show up on the map they're found in fights withspinies or antasmans. In battle, the large Goombas have two attacks; the first has them hovering towards Mario, which must be countered with a hammer, or else Mario will be rendered dizzy. The second attack has them spinning on the ground in a semi-homing pattern towards Mario. Mario can move out of the way or jump over the Big Tail Goomba in this attack. The Goomba can damage another foe if made to strike them, and may make itself dizzy, signified by a more violent spin; in this case, it sits for a second in front of Mario when near him, and then simply walks towards him.
