During the Tropical Wigglers retraction animation (due to releasing your stretch whilst over a cliff), if there is another capture intersecting the Wigglers stretch path; such as Glydon, the Wigglers head will be seperated from its body and after the animation ends, the body will teleport to the head. This happens even if the head is currently clipped out-of-bounds. By placing the object which will intersect your stretch path (Glydon or another Wiggler) close to a wall, the Wigglers head will be forced to clip through said wall. This can be used to clip through any wall in Lost Kingdom. Discovered by Syrkl
In 2-player mode; when in a capture and using Cappy flight, if Cappy interacts with an object that causes the second player to lose control of Cappy temporarily (such as a lamppost, pole, switch, turnip), this will force the Mario player to be released out of the capture they are currently possessing. If this is done whilst directly underneath a ceiling Mario will be released through the ceiling and clipped out-of-bounds. This works for captures: Frog, Goomba-Tower, Cheep Cheep, Coin Coffer, Lakitu. Discovered by Syrkl
When underneath a corner as a Cheep Cheep capture, hold A or B to swim upwards whilst barely trapped by the corners overhang. Now press ZL or ZR to release from the capture and Mario will clip into the corner out of bounds. This can by quite finicky and will require some good positioning as well as luck. Discovered by Syrkl
In the Shiveria sub-room, Hollow Crevasse, you can clip through the far wall close to the water by exploiting the small gap created when a Bitefrost rises. Being on the side closer to the water increases the chance for the wall-clip. One way to do this is to slide down the wall as the Bitefrost rises from the ground and then perform a roll into the wall whilst in the gap. Discovered by Syrkl
By executing multiple Motion Control jumps on slopes as a captured Goomba, you can gain speed exponentially. Discovered by Noguy5
This is for certain Low% categories. Simply setup a Dog Hover near where the Koopa Trace-Walking minigame is. Then proceed to hover for approximately 15 minutes before jumping towards the Moon.
This is useful for Low% as it gets Metro Kingdom Moons: 12, 20 and 60 without capturing the Spark Pylon (Make sure you do this after hitting the Moon Cube). To do this you must set-up a Dog Hover with the Metro Kingdom Dog and Hover for an average of 30minutes. You will be high enough to jump over to the top of Metro City Hall.
Interrupting the Dogs Jump-Animation by bouncing off of the Dog itself will freeze the Dog in mid-air whilst the Dog plays out its Hit-Animation. After this animation ends the Dog will re-do its Jump-Animation at the point it froze in air thus gaining height. You can interrupt this second jump and all consequential jumps to gain infinite height. To do so you must wait a certain amount of time in-between bouncing off of the Dog. A good rhythm is to; - Hold B or A when bouncing on the Dog to do a large bounce - Press Y or X to throw Cappy at the apex of the bounce - Press ZL or ZR to perform a groundpound shortly after This rhythm is seen at the end of the video linked.
Land on the railing north of the manhole whilst riding the scooter. Your angle must be so Mario is facing directly at the wall; bounce once or twice to make the scooter move backward off the railing and as soon as the scooter tilts to a steep angle (Mario facing the sky) hold accelerate. The clip itself is very luck intensive and can take multiple tries. After clipping, immediately jump off the scooter and make your way to the Manhole and loading zone to the Sewer. This skips the Manhole capture for certain Low% categories. Discovered by Mnyush & Syrkl
