How do you defeat the monster in the bizarre room in alice in wonderland world inthe game kingdom hearts

The boss in the Bizarre Room is called Trick Master.
Basically you have to get up to high ledges, like the table. Do not use Fire. I repeat do not use Fire. The things it holds would catch on fire and shoot out fire balls at you. It is annoying. When it is close to you use Lock-on and jump and attack multiple times. It would eventually fall and you can keep hitting it. HP orbs would fly out of Trick Master. Repeat this until you defeat it.

Hope this helps!
