Metroid Invasion
From Digibutter.Nerr Wiki
After Tippi was replaced by a Metroid, some of the Members of Digibutter started adding a Metroid to their Avatars. Shortly after, a Metroid appeared on Everyone's Avatars. This lasted till the end of the day, however, very little members (Fireice) kept it. Strangely, the Member MALAK's Metroid was friendly, and ended up being his pet, called Metroidy.
