ever heard of jumping? no offence thats how u do it m8.........

thanks ive done both, u need to ground pound them 3 times

I cant do it I cant ground pound in time how do you do it?

ummmm.....if ground pound wont work i dunno but just make sure ur double jumping holding and pressing down:)i hope i didnt post this message to l8 cyas....

for world 2, ground pound when it surfaces while its low down.

for world 5, it collapses on the floor so timing is not needed to ground pound. good luck!
