Most opponents are humanoid, a few of which throw items that can be caught.
Non boss opponents are eliminated if Goofy throws an item at them or if Max throws two items at them.
Alternatively, the Grapple gun can stun them.
Such opponents are rather weak, which means even Max can eliminate them with one throw. The Grapple gun eliminates them too. However, they can sometimes fly and thus can't be hidden from.
