Blarggwich

Support Ghosts ("Unbaba Lift" in Japan) are an undead species of Blargg that first appeared in Super Mario World 2: Yoshi's Island. They were rare, appearing only in Sluggy the Unshaven's Fort. Yoshi could jump onto and freely move around atop the platforms carried on Support Ghosts' heads, and the Support Ghost would move along a set path, occasionally stopping and stretching upward (which could lead Yoshi to both traps and helpful items).

Support Ghosts return in Super Smash Bros. Brawl. They appear in the Yoshi's Island stage. However, this Support Ghost perpetually acts as a helpful character, acting as an extra platform over a deep pit. Players can jump onto it to avoid falling. However, it appears only at random moments.
