Desolatt Island Walkthrough

#	Step by Step Objectives
1	After newly unlocking the currents to the Color-Full Sea and discovering its Great Lighthouse, Arc suggests finding and relinking a new island that might hold the key to breaching its steel walls.
2	Sail onward until you discover a drifting island on your Ocean Map, and use the telescope to reveal Desolatt Island! Once you've ensured both brothers are well-equipped with suitable gear, set your course, fire away toward the island, and land on its sandy shores.
3	As Mario and Luigi walk toward the Island's plaza, they will be stopped by four children who introduce themselves as IDLE. While they argue about their introduction, Snaptors holding captives fly overhead to the lighthouse. After revealing that the brothers mean to relink Desolatt Island back to Shipshape Island, IDLE proposes a game of hide-and-seek to test Mario and Luigi's capabilities.
*	If you are having trouble looking for the IDLE kids, you may approach one of the Concordians on top of on of the buildings with a speech bubble. They will cite hints on three kids' whereabouts: ・Loog is inside a blue building north from where you currently are. ・Dulles usually plays in the green building northeast. ・Ellow is in the yellow building to the west of the island.
4	Head inside the green house Northeast of Desolatt Island where you can find Dulles. Although to reach him, you must navigate your way through the hole-trodden interiors of the building.
5	Climb up the green stairs into the second floor and jump down the leftmost hole to lead you back into the first floor, then climb up the green stairs again. Back on the second floor, move forward to a new set of holes and jump down the one on the left. Climb the stairs again one last time, move forward to third pair of holes, and jump down the hole on the far left to reach Dulles. During your conversation, he will give you clues on other IDLE members' whereabouts and set you on your way to find them.
6	Head to the western part of the island to discover Ellow stuck through a doorway in one of the buildings. To help him out of his predicament, enter the yellow building next to an unbloomed connectar flower.
7	Inside, you will find platforms with green squares on the floor. Use the UFO Spin Bros. Move to cross between the gaps and proceed to the building's rooftop.
8	Once more, use your UFO Spin Bros. Move to cross another gap, and walk into the yellow building that Ellow is stuck in via the rooftop. Jump to the first floor where Luigi uses his Luigi Logic to push Ellow out of the doorway, successfully freeing him. With Ellow finally liberated, he points you to the direction of Loog, inside the blue building north of Desolatt Island.
9	Head north of Desolatt Island and enter the blue building where you can find a Grampy Turnip planted by the doorway.
10	The area inside the building is dark, with only a light switch to your left illuminating a small patch of the room. Hit it with your hammer to open the lights, and navigate your way to the right side of the building. Do note that the lights only stay on for a limited number of time before turning back off. In which case, you must find another light switch to keep the area illuminated.
11	With the lights on, hop on every blue crate and use your UFO Spin Bros. Move to cross wide gaps until you reach Loog who is standing by the doorway to the right side of the room. After finding and speaking to him, he will lead you outside, where all members of IDLE are gathered.
12	All IDLE members open the gate to a path that leads directly to the island's lighthouse. Be sure to hit the Save Block and Recovery Block on your way to the lighthouse, as there will be a boss fight soon after.
13	Upon reaching the lighthouse, you will be greeted by none other than Zokket and the Extension Corps. Ten steps in to derail your plans, proceeding into the island's major Boss Fight. ★ Battle Tip! Beating Ten When Ten summons mirrors on the battlefield which bounce electric balls, focus on which colored mirror the balls hit last to determine which brother needs to counterattack. Red is for Mario and Green is for Luigi. If Snaptors appear on the battlefield, pay them no mind and instead focus all of your attacks on Ten, as he resummons the Snaptors eitherway if one of them is eliminated. ▶︎ How to Beat Ten
14	After defeating Ten for the first time, he drops a Power Tap and Battle Plug. Upon discovering this, he returns once more to try and reclaim it from the brothers, though this only serves as a demonstration to the power of the Kaboom Attack Battle Plug, and he retreats immediately upon getting hit.
15	Snoutlet will introduce the concept of Battle Plugs which can be crafted with the use of all Sprite Bulbs you collect while exploring. You can pick whichever on you would like to craft, although we recommend the Surprise Iron Ball or Dizzifying Attack first, depending on how much Lumenade you have available. ▶︎ Best Battle Plugs to Buy First
16	After following Snoutlet's tutorial on Battle Plugs, head toward the lighthouse and relink Desolatt Island! A cutscene will play afterward, and you will be transported back to Shipshape Island.
