Miniree

A Miniree, likely a small Skree, is an unused creature from Metroid Prime 2: Echoes. Only the name exists in the data, and has absolutely no other programmed data at all. It may have been replaced with the Shriekbat Infant during development, before being cut entirely.

Artwork for unused Skree variants survived in Metroid Prime and Metroid Fusion: Prima's Official Strategy Guide.
