Talking to this dude whilst on the house can softlock the game. (Normally works in the first 3 tries or so)

Ground pound rolling towards a wall when breaking a box can clip you through the wall.

Opening snapshot mode, the map, or the menu on a certain frame when uncapturing binoculars causes the UI (coins, compass, etc) to disappear. It reappears when you open another menu or capture anything.

Unloading one of the cutscene frogs after cappy lands on it makes the game crash.

Going through this corner in the Cap Kingdom let you just go through the wall, since the collision was too intricate. Patched in version 1.2

Accidentally found this in one of my Talkatoo% runs. I'm not sure if this is already common knowledge (I have never seen this before), but it seems that with the right combination of speed and positioning, you can essentially perform a Triple Jump underwater here in Lake, allowing you to preserve your speed well into the water. This could be situationally useful in Talkatoo%, so I intend to lab this out soon.

Clip for OOB in the Sand Kingdom (near Tostarenean Ruins Entrance) by exploding a skull sign via bullet bill and standing in the destroyed sign before it spawns in, clipping you below the quicksand. Can be done with both signs near the entrance. Can't confirm if it can work with other skull signs, for example the ones in and around Jaxi Ruins.

You can gain infinite height in Metro Kingdom by abusing the Hat object. (This object is on a bench east of Pauline after achieving peace. It disappears once you collect moon No.57) You need to jump and immediately throw the Hat with Y, then dive towards the Hat and on the frame you bounce off of the Hat, press Y to pick it up followed by a second Y press to throw the Hat again and repeat the process. The Y press to pick up the Hat when bouncing on it is difficult and only has a window of about 2 frames.

This glitch utilizes the "Roll Cancel Clip" to clip through the door of the Inverted Pyramid allowing the player to break the sequence of Sand Kingdom and skip 2 story moons. Used in longer speedrunning categories such as All-Unique-Moons and World-Peace. Discovered by Syrkl

This trick utilizes "Turnip Clip" to clip through the box guarding the second story moon of Luncheon Kingdom. Clipping method discovered by Mnyush. Clipping spot discovered by Syrkl.

By placing a Turnip very close to a wall, releasing a Panbro over said turnip, then lastly re-capturing the Panbro, it is possible to be pushed out-of-bounds. It is possible to achieve this with only a single Turnip as-long as good placement is used. Discovered by Mnyush.

This glitch is a clipping method which allows the user to get OoB in many locations where there is a slope leading into water. The inputs are very similar to "Roll Cancel Clip", the only difference being you need to move the analog to guide Mario towards the wall you wish to clip through. Discovered by Mnyush.

This trick utilizes Roll Cancel to clip through certain walls and surfaces. You must be very close to the wall you wish to clip through, Then perform the inputs correctly listed in the video. Discovered by Zinpars.

This glitch uses Yoshi's tongue to push Goombas out-of-bounds, you can also use the spot in the video to capture the goomba whilst it is OoB and remain OoB. To do this, place a Goomba close to the wall you wish to clip it through, then attempt to eat the Goomba with Yoshi but immediately cancel the Tongue animation by releasing the Yoshi capture (press ZL or ZR).
