Simply pick up the Mushroom blocks that lay on the ground (with B if you don't know) and throw them at him. He will split into smaller flames which you must defeat too. These are faster than the original Hot Head.
This boss is quite difficult so don't be disappointed if you lose a few lives attempting to defeat him.
easy when he pops up from the ground then get above him and ground pound his head
first, you have to stomp (jump first and then push z when you are in the air). when he gets dizzy, spin into him.
If you have flower power it takes between 9 and 13 shots to kill however if you are super Mario you must jump on its head 3 times but if you are normal Mario or mini Mario you must do 3 ground pounds on its head to kill it.If you are mega Mario you just step on it and it dies.
A Bee
beat the bowser junior monster in w3 last castle by double jumping on its head and destroyingi then u go to w4
In New Super Mario Bros, jump using A and press down on the control pad while in air.
Well, avoid the koopaling attacks when he ground-pounds by jumping. When he lands, I suggest you jump on his head right away.
jim on top of his head
hit him in the back of the head with goombas
When his head pops up do a ground pound near him. Then spin into him. The first time he will be sitting, but be prepared because he wanders around both other times after.
You have to stomp on the bosses head
