Car Stacking
Cars have multiple spawn locations if you're not currently in one. You can abuse this to get more than one car. However if you stay in a car while another one is on screen, the other car will despawn. This means you have to instantly spit them out to prevent them from despawning. If you manage to get two or more cars stacked with this, they can glitch out. A good place to do the glith if you want to play with it is the tutorial. In the video under you can see an example of how to do the glitch. Remember you can insta-spit with -.
Mouthful Storage
Take damage the moment you start sucking a mouthful object. This will cancel the animation for entering mouthful mode and let's you walk freely. This lets you enter mouthful mode from a distance. This glitch can be done one any object that would let you enter mouthful mode as long as there is a way to take damage while sucking. Under you can find a video of the glitch.
Mouthful Warp
If you wedge yourself in a space where mouthful Kirby won't fit and then start sucking to enter mouthful mode you get warped to the mouthful objects point of origin. This seems to be less of a glitch and more of safety measure put in the game by HAL in case off situations like this. Example below.
Of course peole realized that this mechanic synergised well with the mouthful storage glitch and it was found that if you perform a mouthful storage and then wedge your self in a space you still get warped to or somewhere near a mouthful objects point of origin. Going to far may lead to the game crashing. Video of glitch below.
Cone Double Jump
If you press jump right after turning into a Cone, you can perform a jump midair. This glitch is also what makes the Thirdle skip possible, but instead of jumping the moment you enter Cone mouth stage, you instead you have to jump at a spesific frame after getting hit(more info on the Turtle skip page). Video of the regular Cone jump below.
Alivel Mall (Staff Side)Out of Bounds
Using a Cone Double Jump from the overhang at the end of the level let's you make it to the side overhang where you can use the cone to jump out of bounds
Tropic Woods Cutscene Skip
This glitch is a bit finicky but to do it go to the fourth to last pole and position kirby so that he is barely not behind it then do a dodge jump upwards slightly tilted to the right before quickly tilting it right facing a bit upwards. Try to replicate what the video below does.
