These are Epic Plant Wubbox's Cousins,
1. Epic Cold Wubbox
2. Epic Air Wubbox
3. Epic Water Wubbox
and 4. Epic Earth Wubbox.

The Epic Wubbox is the antithesis of the Rare variant, who traveled abroad and became more in step with the technologies and forms of communication of the human world. Instead, it communes more deeply with its host Colossal's Elemental affiliation than any of its cousins, which is reflected both in its appearance and in its musical performance. The Epics who shrunk down.
