Past
A legendary relic, the Tummel Crystal became renowned for being able to power any kind of mech suit. Lore claimed it was buried in the catacombs deep below Buddy Buddy Temple.

In the present day, the Tummel Crystal was sought by Charlie to power his mech suit. After he told about it to Dr. Eggman however, the doctor excavated it from its catacombs with the aid of the Froglodytes and some enslaved Gogobas, and used it as a power source for MeBot.
