Throw Bob-ombs to destroy all the trash piles within 30 seconds to get the hidden star. Feed it 30 star bits and it'll TRANSFOOOORM into a launch star to the garbage dump. When you reach the multi-coloured planet made up of orbs, during Breaking Into Battlerock, you'll find another hungry Luma. Can't find you a picture of the Garbage Dump, but here's one of the lava thing from earlier. You can shoot the yellow targets on the floor for a quick coin top-up during the fight as well. If you're struggling, there's a Luma right next to the boss battle arena who will sell you an extra life or a health power-up for 30 star bits. Do this - you guessed it - three times, and the star is yours. Once you reach Topmaniac, in a showdown that will be familiar to anyone seduced by the Beyblade craze, you simply have to jump on the centre - avoiding the spikes - and then spin it into the lasers. The trickiest parts of this level are bouncing the spinning tops into the lasers and navigating another gravity-flipping 2D section filled with rotating platforms and lava. Aim yourself at the power star, wait for a clear shot and away you go.

Then its simply a question of carrying a Bob-omb from one end of the rocket to the other - it's easier to jump over the electrical barriers rather than finding the gaps - and blow open the last cannon. Drop in, aim yourself at the floating crystal in the middle and fire away to free a Luma and get another launch star. Once you reach the Battlerock, just jump down the pipe and then stun and throw Bob-ombs to open up the cannon hole. There's a Super Mario mushroom on the coloured orbs, which should keep you invincible just long enough to plough through, should you struggle. After the multi-coloured orb planet, you'll have to navigate a minefield using pull stars, which isn't too tricky provided you go slowly enough not to build up too much momentum. You'll be using them a lot in this level to blow open cages, so get used to picking them up and then navigating past obstacles in order to throw them where they're needed. Welcome back to an old foe - the Bob-omb. Once you reach the end, it's time to use our old pals, Bullet Bills, to smash open those domes and snaffle the goodies within. You can duck under the girders, but the electrical fields can only be evaded by running to the underside of the disc. As well as avoiding the cannonballs, keep your eyes on the obstacles that are headed your way. Spin on top of this to set it in motion, and then get ready to dodge the barrage. Leap from silver disc to silver disc, until you reach the one with the blue screw. It's all about the over-under on this one.
