idk if this is a stupid idea for an enemy but here are some i got
1. an enemy that can stretch its tounge like Yohsi to catch you further away
2. an enemy that is mad like burning mad and you need to suck on him with your wand but not flash it to cool him down and then he goes away
3. an enemy that wont hurt you but it will jump on to you and block your view for a few seconds or maybe you can try shake it off
4. an enemy that just steals you money and tries to run away and if you dont catch him in time he disapears and you lose the money
5. a friendly ghost that can be paid to protect you
6. an food item that makes Japes faster for a short time
