The Laundro Mobile is the seventh major boss of Sonic Mania, fought at the end of Hydrocity Zone Act 2. Doctor Eggman is back in an improved version of the Big Shaker from the original Hydrocity Zone in Sonic the Hedgehog 3.
This boss fight comprises two distinct parts requiring different strategies. First, Eggman pursues the player through Hydrocity's winding underwater tunnels. Bourne along by the currents, it is not possible to curl up for a spin attack and attack the boss directly; but, in the same way, Eggman doesn't directly attack the player, content to let the various spike traps do their work for him. Bit within the tunnels are also floating bombs which can be activated by bumping into their buttons. The player must then bait Eggman into crashing against these primed bombs, damaging his machine. This also releases much-needed air bubbles, which can't otherwise be obtained during this part of the fight.
After enough damage is done, the side-scrolling segment ends and the player is dumped into a very familiar basin - the same one as from Sonic 3. Eggman then powers his machine back-and-forth in the u-shaped pit, periodically stopping to dock with the central pillar and swirl around the waters. Attacking him as he engages and disengages this lock-on is the path towards victory.
