DeluPipi

DeluPipi was a hazard, alongside Met, on Castle Wily (now known as Skull Fortress) in Super Smash Flash 2. It was removed from the stage when it was remodeled as Skull Fortress, however, Met remained in there.

In Super Smash Flash 2
This is variation of the common Pipi enemy seen in the game Mega Man 7. DeluPipis are robotic bird that drops egg-shaped capsules filled with Child Pipis that damage everything they touch. As they are flying enemies, the most recommended weapon to defeat them is the "Metal-Blade".
