>>110101367>one that he knew for one day, maybe lessIt's unclear how much time they spent together in the forest, it could've been months for all we know. Also, it doesn't matter how much time he knew her, see pic related. His parental instincts kicked in when he saw Bobo for the first time, and I guess it's kinda hard to blame him, since she's cute af and she has that robot-like arm that looks like Badgerclops's.
He was determined to protect her, but failed, and she was in real danger of getting eaten by a bigger monster. Either way, there was no guarantee that he would see her again. IMO, that's a legitimate reason to grieve for three months, and Mao Mao was being an inconsiderate jerk, and Adorabat was being even more of a psycho than usual, it was actually kinda creepy.
