Help!!!!!!!!!

Have you noticed those blue circles of glass? Stand on one of those and wait for Bowser to use his jump and stomp move. Dodge as he's coming down, he'll crash into the glass and break through to the lava underneath, lighting him on fire. He'll run. Head him off and spin into him, sending him spinning the other way. Head him off while he's spinning and spin into him again to damage him. Repeat 3 times, but sometimes when he's spinning you'll need to hit him more than once.

When your fighting him on the planet there is blue circles. Keep running away from him intill he jumps really high.When he is in the air stand on the blue glass circle and then run away just that second before he hits the glass so you won't get hit.Then he will hold his tail while on fire,spin bowser when that happens he will spin around fast. Stand on a spot where he spins around the planet then spin him before he spins into you.

Thats how you do it coz I did it that way. If you still can't do it then look on youtube.

what is the ? star on deep dark galaxy the undergroung ghost ship?

Bowser will do his "ground pound" every now and then. Make him ground pound on one of the blue glass circles. There is lava underneath and he will set his tail on fire. Wait for him to run to the other side of the planet instead of chasing after him. Spin into Bowser's tail. Spin into Bowser again. Do this 3 times. The third time, however, you need to spin into Bowser's tail, and then spin into him 2 more times to beat him.
