He came down from Heaven one day by shinning down a tree. Not a very dignified entrance for a Sky God, but it takes all sorts.
But while on a Heavenly visit to see his dad, AHOEITU was ambushed by his jealous half brothers. They were so jealous that they ate him.
EITUMATUPUA was very cross indeed when he found out and the culprits were punished by being forced to regurgitate and then watch as AHOEITU was lovingly reassembled by his doting father. Furthermore they were grounded, or in this case heavened, and never allowed to visit Earth again.
