A nightclub-esque Public room, Club Mammoth was first opened to only HC and VIP (when it was introduced) members. It was mainly used for celebrity visits, but also functioned as a popular exclusive hang-out spot for Club members. When popularity dropped, Sulake changed it so it was accessible to all members, then finally shut it with the introduction of Habbo Beta.
The room description was "Monumental and magnificent."
- Redesigned and re-opened as House of Flying Carrots
