I think that Munku is the unofficial leader of the Jellicles, because 
lately Old Deuteronomy has had to take it really easy, he's getting 
old! Munku does everything but make the Jellicle Choice for him, 
which I think is a little unfair! As to his family, I think that 
Bustopher Jones is either his father or Uncle, and that Deuteronomy 
is his paternal Grandfather. It is my theory that Tugger is his half 
brother, and Misto could be either half or full. I also think that 
the Great Rumpus Cat is related to him somehow...I have two theories 
about this: 

1. (probably the most likely) Tugger is The Rumpus Cat's father, 
making Munku an uncle! 

2. Munku is Rumpuses father, but I have absolutely no idea who the 
mom is 

Munku is one of my favs, and is definitely headed for a future as 
Jellicle Leader!
