Kukkubee just stated in Global that either 'later this week or early next week there will be new cubimals'!!! He also said that he has already made them... so any guesses?
Things guessed so far (NOT THE REAL CUBIS...JUST GUESSES!):
-Moose
-Bacon Cubi (lol.. i wonder who guessed that ;)
-Hell's Bartender
-Fox
-Sloth
-Ranger
-tool vendor
Kukkubee has stated below that these ones are NOT related to the giants...
(also, if anyone has a snapshot of it could they please post the link)
UPDATE #1: I added a list of guesses.
