Head to the underside of the first planet. Walk round until you see the orange pipe. Jump on top of it to go down. Use the ramps to get to the ? coin, which will leave a trail of notes behind it. Collect all the notes for a 1-Up mushroom. Head through the orange pipe on the ceiling to emerge on top of the house that you face when you first arrive in the level. Use the Launch Star just above you.

Smash the crystal containing the Toad on the next planet - he reveals that the green balls are supposed to be coconuts(!). Spin the coconuts into the spiky enemies and one of them will turn into a small Launch Star. Use it to get to the nearby planet.

There's a Pokey on this planet: spin a coconut into him and he'll fall apart. Jump on his head and he'll turn into a Launch Star.

You land in a small Launch Star - use it.

Move onto the top of the planet and head upwards. Smash the crystal, which will reveals a Launch Star. Use it. You're now at the Battle Fleet of the title!

Two enemies will fire coconuts at you from the ship immediately in front of you. Spin into the coconuts and they will fly back at the enemies, destroying them. This lowers a bridge to that other ship. Head over and to the right. Smashing the crystal you find reveals a Launch Star. Use it.

Move round to the top of the planet to meet King Kaliente. Avoid his fireballs, which are red, and spin his coconuts back at him (they're green). After the first hit, he will start to reflect the coconuts back at you - get into position and spin them back at him, as many times as you need to. After 3 hits total, he's beaten. Move round the planet to the Power Star and collect it!
