Green lizards aren't attacked by regular vultures so they aren't scared of regular vulture masks (even though they are scared of vultures), instead becoming temporarily pacificied until they recognize slugcat.
“I can’t tell if that’s either a vulture or a slugcat…. So I don’t know whether or not to run or chase it….. hmmm…. Oh whatever, I guess ill just chill here”
green lizards aren't hunted by vultures, so they ignore both vultures and their masks. this results in them becoming docile if you wear a mask near them.
