Yellow Switch
From the Super Mario Wiki
Yellow Switches are rare objects that are found in the Vim Factory during Mario & Luigi: Partners in Time. They are so very rare, in fact, that only around two to three appear in the game. They have two little blocks on them, meaning that both Baby Mario and Baby Luigi can stand on and open doors. They are a variation of the common Blue Switch.
These switches also make an appearance in Super Mario Advance 4: Super Mario Bros. 3, in which Luigi will gain his Flutter Jump ability from Super Mario Bros. 2.
