for some reason while its alive the fiery tank can be grabbed at the base by the gravity gun but not the physgun (neither the soft or creative mode versions). im unsure if the gravity gun is working and the physgun isnt, or if the physgun is working as intended and the gravity gun shouldnt be able to acquire it
cyboars can be grabbed by both guns but the hitbox for the physgun is inconsistent at close ranges. its probably the skinned mesh not aligning with the actual hitbox
also, dont know if its intentional, but cyboars can be VERY easily killed with a pressure washer. ive only tried it with the ariral one but i assume it works with the human pressure washer as well. i think its because it pushes them back with enough force they take impact damage on the ground/walls and its not that the water itself hurts them.
