Throwback Throwdown
In this galaxy you compete against well-known final opponents from the predecessor. First you will meet Dino Piranha, whom you have defeated before. So it's not a problem.
In the next fight against the big octopus (King Kaliente) you have to dodge the fireballs and shoot the green ball back by shaking attack. After the second hit there are two bullets, after the third three. At the end, a Launch Star appears. But first run to the bottom of the planet and grab the Life Mushroom and the Comet Medal.
The helmed mole (Major Burrows) is stamped out of its hole as soon as it approaches you. Then give him a strong shot per spin. You have to repeat the whole thing three times – of course he gets angrier every time and thus faster.
In front of the stone monster (Bouldergeist) you will finally find a Checkpoint Flag. In battle you dodge his stones and grab one of the black spirits with a spin. Now catapult him three times against the creature. In the next phase, it now has two hands – the principle remains the same, only it will be harder to hit. You can also destroy the hands, but they grow again.
Ultimately, you will compete again against Fire Dino Piranha, but with the subtle difference that the monster is on fire. So you can only kick the tail if you go out for a short time.
Throwback Throwdown Speed Run
Select this challenge when the Prankster Comet appears.
Clatter off all boss opponents again and finish them all – but this time within five minutes. After the first two, the limit of four minutes should not be undercut, otherwise it will be extremely close. The stone monster takes the most time. Here you need a lot of skill to hurl the spirits against the body as quickly as possible. Just perfect your technique and take your legs in your hand – then it should work!
Comet Medal
At King Kaliente’s planet, walk around to the underside of the arena. The medal is there beside the Life Mushroom; take it before launching to the next boss.
Green Stars — unlock requirement
Collect all 120 regular stars and defeat Bowser again to unlock the Green Star hunt. Choose the corresponding Green Star mission from this galaxy’s mission screen. Follow the detours below rather than collecting the normal mission’s ending star.
Green Star 1
On Major Burrows’ planet, climb the tree with a wall jump or backflip. Add a spin near the top to reach the star above its branches. You do not need to finish the entire boss gauntlet first.
Green Star 2
On Bouldergeist’s planet, go around to the arena’s rear edge and locate the star below it. Defeat Bouldergeist first if you want a clear approach, then drop carefully from the back of the circular platform.
Check each numbered Green Star on the mission screen after collecting it. The routes finish immediately when the star is touched, including stars suspended over a gap.
