I beat robo bear challenge round ten...
...as a mixed hive!
THEY SAID IT COULDN'T BE DONE BUT I DID IT
I had to use stingers and demon mask to kill the cogmowers, and i chose white pollen for the quest because my moon amulet has +109% pineapple patch pollen. the cogmowers were in strawberry, pumpkin, and luckily, pineapple! so i killed them in straw and pumpkin, then went to pineapple, and used a glue and stingers to kill the cogmowers and get pollen.
Any tips for rounds 11 and up?
