How do you get ghost Kirby ability on Kirby squeak squad?

Answer 1

To get the Ghost ability, you must complete the Ghost Medal. Finding all the pieces is based upon luck, from what I've seen. Once you complete the medal, the minibosses at the following stages will be replaced:

1-3, 3-2, 4-4, 6-4, and 8-1.

It's reccomended to use abilities that let you pass through an enemy such as Tornado or Hi-Jump. After you beat him, you can inhale him to get the ghost ability. Also, once you complete the medal, you can combine the Sleep ability with another Sleep ability to get the Ghost ability. Under normal circumstances, this would result in the Ninja ability.
