People teleporting and going through floors
From Glitches
From the game Paper Mario for the Nintendo 64.
Go to Mario and Luigi's house. Now, stomp on the section of the floor that lets you go to the hidden basement and read Luigi's diary. As you go through, try to keep your partner on the upper floor. Now, walk around alone in the basement and your partner will suddenly warp to you. Or, you can do it the other way around - bring your partner to the basement but them leave him/her down there when you go back up. Sometimes you can even get them to hop down from above when you're going up from below. With some characters, like Boo or Parakarry, it doesn't look too weird - but they go through the floor/ceiling to get to you. With others, like Kooper, the character suddenly and glitch-ishly disappears from their spot and appears next to Mario.
