While Mario is non-negotiable, the other two members of your party can be swapped around. For the first part of the fight, we highly recommend bringing in Geno and Peach. Geno is needed for his Geno Whirl move as it can one-shot the powerful Snifsters, and Peach can Mute them, helping your party to take less damage. After you defeat the Snifsterss, we do advise switching to Mallow, as he can use Snowy, which Booster is weak against, to finish the boss battle with ease.

How to Defeat Booster and The Strong Snifsters Rematch¶

This fight is incredibly difficult at first, and you will likely get quite a few game-overs before getting down the perfect rhythm. The fight pits you against four enemies in total, Booster, and three Strong Snifsters. Booster only has a single attack, but it will wipe your on-field party. The key to the battle is to keep him from using this ability by interrupting his concentration. This can be done by hitting him with a normal attack directly. or using multi-hit special attacks like Geno Beam. Each round, one of the Snifsters will use Morale Support. This move sets Geno up to start working on his train quickly.

When you see the words “Booster it seems to be up to something…” interrupt his concentration on your next turn, or he will use Loco Express 023 on your entire on-field party. While you are keeping Booster under control, the other two Snifsters will be focused on attacking you with a multitude of attacks, like Bolt, Gunk Ball, and Blizzard. These are common attacks that you’ve already seen in the game, and with a bit of healing from Peach, you can easily work your way around the damage you receive.

The key to this battle is to use Geno Whirl while executing its action command to hit a Snifster for 9,999 damage. You will need to do this three times to wipe them all out. To help negate some of the damage the Snifsters deal out, use Peach’s Mute to cut back on the special attacks they can use. Mute won’t stop them from using Morale Support though, so you will still need to break Boosters Concentration. Here is a quick rundown of how the fight should go.

• Your priority is breaking Booster’s concentration.
• Once you are safe, use Geno Whirl and execute an action command to wipe out the Snifsters one by one.
• Use Peach’s mute to help control the amount of damage the Snifsters can deal.
• Once you only have Booster left on the field, switch Geno for Mallow to use Snowy.

Once Booster is alone, switch Geno out for Mallow. Booster is weak against Ice moves, so using Snowy will make quick work of him. Booster will still attempt to complete his train when he’s on his own, but you can simply attack him to stop this process. Below is a quick look at all the moves you will face in the battle. Along with these, the Snifsters have a basic move where they shoot a bullet bill at a single party member. All but one comes from the Snifsters, and for the most part, these are basic moves that you have encountered before.
