There was a joke that happened in the last DnD session with Momolop and Regi.

Momolop met another player for the first time and he was explaining Regi and how Regi was his 'underling'. THe other character asked if he was a slave and Momolop replied That he doesn't make Regi do mundane things like brush his ears.

The DM maid a gesture for Regi that was him reach behind him and pulling out a hair brush and quickly putting it back.

So, it's now cannon that Regi brushes Momolop's ears from time to time.
