I assume you mean control with the Ghost ability. You cannot control Bosses or Mini-bosses with Ghost. Only regular enemies.
The star is the final boss.
Unfortunately, he cannot. Kirby can, however get something called Triple Star after the final boss.
After you get the ghost medallion, Boxy (the present boss) is replaced by Tedhaun (the ghost boss) in every level where she originally appeared, except for a room in the extra level of Secret Sea. I don't know which room, however. Source: Kirby Wiki
You have to beat the last boss to get it
you have to get all the ghost medal fragments which can be found inside different treasure chests. Then to get the power, u can go around the different stages looking for a ghost boss.
When u get all the pieces of the medal, u can defeat the ghost boss in each level to gain the power 'ghost' im pretty sure the "action replay" has a cheat for that
There are 8 worlds. Counting the extra levels and boss levels, the first 4 worlds each have 7 levels. World 5 has 6 levels. Worlds 6-7 have 7 levels each, and World 8 has 4 levels. That adds up to 52 levels.
you have to defeat then swallow the cook boss
Once meta knight and kirby were friends. But Kirby accidentally bullied meta knight so he got his sword, mask, cape, and armor and tried to kill kirby. Kirby did his best to say sorry to meta knight but he wont listen and kept on trying to kill kirby.
After you beat a boss in almost any Kirby game he jumps around and spins a bit.
Meta Knight is basically a blue Kirby with white eyes without his mask. When his mask is on it has a yellow tint so it makes his eyes appear yellow. He also wears a navy blue cape and purple shoes and has a shiny golden sword. SHINY!You can see Meta Knight without his mask in Kirby Super Star Ultra in a level that is like a tournament if you defeat him his mask falls and after a few seconds he leaves hope this helped.He also reveals his identity if Kirby squeak squad, when you defeat him in the watery area in the boss stage, it falls off and he panics and leaves, so look quick!
