Quick, Mario! Get my magical game entering portal! It's just over there. It's the answer to all our problems!
|—Bowser telling Mario about the portal.|
Bowser's Magic Game-Entering Portal is a portal owned by Bowser which first debuted in SMG4: The Fan Written Episode (4 Mill Sub Special). As it's name suggests, it allows people to transport themselves into video games.
Bowser's Magic Game-Entering Portal is a golden portal with a blue gateway.
The portal's gateway can lead towards any video game world, such as Super Smash Bros.
The portal first appears in Fresh Spaghetti Tubbie, where Bowser tells Mario to use it to stop the Xenomorph (disguised as Swagmaster6969696969). However, the Xenomorph stops him before he can reach it, which leads to FightingMario54321 and Cube the Penguin burst in to defeat the Xenomorph.
Later, after Mario helps them defeat Fuego the Water Bottle, the Super Mafia Bros bring in the portal and use it to finally grant Mario's wish and put Spaghetti in Super Smash Bros.. The Super Mafia Bros then transport Mario to the Miiverse stage so he can take the Fitness Gram Pacer Test under Ruffman8890's supervision. After he completes it and spawns the Inverted Mario Clone in the process, Mario returns to the Mushroom Kingdom through the portal, where he is then whacked to the moon by his clone to retrieve his soul from FightingMario54321 (which he gave to help defeat the Xenomorph).
