This was originally part of some VHS phone peripheral thing, and also it's made for five year olds who can't count. But because it's obscure Mario lore I had to watch it and see how it ended up... except that it interrupts the story every thirty seconds with a new math quiz, so you don't even get the chance to take in the very low production values.
The big selling point for this one is Iggy Koopa's voice. When I heard it I cracked up laughing, for like two straight minutes. Seriously, please watch this for Iggy alone. Also if you have any children under the age of 6 you may be able to use this as an educational tool.
