Collision between the player & enemy is disabled while the player is off the ground; unless there is a (target) touching the enemy. If you would like to send a video of the issue to my twitter I would be more than happy to fix it :)
It’s okay. The opossums do damage the Coop if you’re not fast enough :) this serves as a purpose for the player to not get bored standing in one spot allowing missed opossums to despawn. A cut scene of them marching away with the egg is in the works!
