Maintenance pet is a Monkey (before, Panda) and has a Construction Hat and holds a red Screwdriver. It has Monkey's main color and when you see him next too "Oops!" you should watch out as it usually doesn't mean anything good.
Panda use to hold the same Screwdriver and wear same Hat but the only difference is that he is a Panda, has its main color and wears Overalls. Just like Monkey, seeing him next to "Oops!" message, signs danger.
