Magic pendant

The Power Pendant is a pendant created by Kooky Von Koopa that could bestow the ability to use Power-Ups to anyone, though only on Earth.

In The Adventures of Super Mario Bros. 3 episode "Super Koopa", King Bowser Koopa uses the Power Pendant to cause havoc for Mario and Luigi, becoming Fire Koopa, Raccoon Koopa and Frog Koopa, along with being able to ride in a Kurubee Shoe.

Eventually, the Power Pendant became to strained after being used several times consecutively by Bowser and overloaded before exploding spectacularly.

How the Power Pendant works is relatively unknown and why it only works on Earth is a mystery as well. Along with giving someone the ability to use Power-Ups, the Power Pendant could seemingly create them. By zapping an object from with Power Pendant, a Power-Up would appear in it, similar to how Power-Ups are found inside Super Blocks; the exception to this appears to be the Kurubee Shoe, Bowser simply needed to zap a rather worn looking boot to transform it into a Kurubee Shoe. Also, it seems after someone has already used a Power-Up, they simply need to zap themselves to use that Power-Up again, instead creating another Power-Up from scratch. The Power Pendant could also, seemingly, allow someone to use multiple Power-Ups at once, such as when Bowser became Fire Bowser and Raccoon Koopa at the same time.
