The Gatekeeper is the keeper of the Volcano. Before Mission 1 was available to everyone, you would have to complete a mini mission and help him get his ruby back from the 'For Rent' building. He was seen at the Christmas Grotto and he is from the Keepers family, which includes the Hatekeeper and Datekeeper.
Supposedly born in Tikkihaha the Gate Keeper has family!!
Which includes his cousin, the Hate Keeper and rumored sister, the Date Keeper. His ruby is also said to be made from pure magical elements of which we do not yet understand.
The Gatekeeper has nobody – literally, because he's just a head. But that doesn't stop him form watching over the entrance to the Super Moshis' volcanic HQ 24/7. Said to have once topped the tallest totem pole in TikkiHaahaa, this key-loving guardian is a stickler for rules: if he doesn't like the look of you, you're not getting in – it's more than his job's worth!
