A Blarggwich, also known as a Support Ghost, is an undead species of Blargg that first appeared in Super Mario World 2: Yoshi's Island. They were rare, appearing only in Salvo the Slime's Castle and Sluggy the Unshaven's Fort. Yoshi could jump onto and freely move around atop the platforms carried on a Blarggwich's head, and the Blarggwich would move along a set path, occasionally stopping and stretching upward (which could lead Yoshi to both traps and helpful items).
Blarggwiches return in Super Smash Bros. Brawl, where they appear in the Yoshi's Island stage. This Blarggwich perpetually acts as an extra platform over a deep pit, and players can jump onto it to avoid falling. However, it appears only at random moments.
