Here, I'd like to list all the mistakes I've found in the Super Mario World cartoon. I must note that this is an episode-specific error listing. If you have any errors yourself, just put them under this thread.
1. The new enemies from Super Mario World are never called by their real names. Here's a chart.
Chargin' Chuck: Koopa Football Player
Sumo Brother: Fire Sumo
Wiggler: Caterpillar
Banzai Bill: Magnum Bullet
Volcano Plant: Fire Plant
Rex, Dino-Rhino, Dino-Torch: Dinosaur
Magikoopa: Koopawizard
Mecha-Koopa: Mech-Koopa; Koopa Robot
2. Luigi's hair is black.
3. Yoshi acts and talks like a baby. As we've seen in Super Mario World and other games, Yoshi should be talking normal English.
4. Now Larry’s hair is light green!
5. Dinosaur Land is called Dinosaur World in later episodes.
6. The Vanilla Dome is called the Ice Dome.
7. The Forest of Illusion is called the Enchanted Forest.
8. The Valley of Bowser is called the Neon Valley.
9. Cavepeople?! There should be other Yoshies!
10. Power Balloons are called Magic Balloons.
11. "Mama Luigi" has the most mistakes in any episode, which is why its mistakes are listed here first. *Green* Yoshi pops out of an egg with *red* spots.
12. Luigi jumps on a Blargg. That couldn't happen in the game.
13. A Torpedo Ted chases Luigi and Baby Yoshi on the surface. Torpedo Teds can't chase Mario or Luigi on the surface of the water in the game.
14. The Wigglers look as though they've already been stomped on.
15. When the Mario Bros. and Yoshi enter the Neon Castle, the Big Boo is circling the top. That should be the Koopa Clown Car.
16. Yoshi enters the Neon Castle, which is something he can't do in the game!
17. The Mario Bros. and Yoshi wind up in the Back Door part of Bowser's Castle. Mario has to give Luigi a boost to hit the Spotlight Block. In the actual level, the Spotlight Block isn't really that high up.
18. Yoshi is shown eating Chargin' Chucks and Mecha-Koopas. Yoshi can't eat Chargin' Chucks in the game. And he can't eat Mecha-Koopas either. (He probably could, but he never enters any of the haunted houses, castles, or fortresses, so I don’t know.)
19. Yoshi (as a baby) is walking on his own. Also, he eats more than five enemies in this episode and doesn't grow into a big Yoshi.
20. Luigi gets squished by a spiked pillar during the chase sequence. Then Mario rolls him up like paper and revives him by touching him on a Power Balloon. First of all, if Luigi (or Mario) got squished by spiked pillar in the SNES game, he’d die instantly, no matter if he had a power or not. Secondly, there is no Power Balloon in Bowser's Castle.
21. Now Yoshi eats fireballs!
22. In "The Wheel Thing", when Mario says "There must be something we can do to make their life easier", it looks like he’s missing his left arm.
23. In "Send in the Clown", the Clown Car’s eyes are blue. They should be yellow.
24. When Bowser says "A circus isn’t a circus without a dinosaur-taming act!", Morton is still wearing his ringmaster suit. When Bowser tells him to "bring on the dinosaurs", Morton comes into shot without his suit! How did he take it off so quickly?
25. In "King Scoopa Koopa", there are different colors on the Rexes.
26. When Mario says "They took our treasure chest too!", he’s talking in Peach’s voice.
27. Peach bashes a Block and out comes a Springboard. Springboards don’t come from Blocks.
28. When Mario is wiping off the coconut milk from his head, he wipes off his sideburn!
29. When Koopa retreats, he takes the cave-people's money with him. But Mario and Peach don't even bother going after him! What's up with that?!
30. In "Rock TV", we can see that Magikoopas hide in the Rock TVs. Yet when Mario and Luigi's Rock TV breaks open, the Magikoopa who was hiding inside has somehow vanished!
31. Right after the Bros. collide into each other, Mario now has green instead of red and Luigi has red instead of green. (Possible explanation: Getting their colors mixed was an effect of being slammed into each other.)
32. Peach bashes a Block and tiny Mario clones come out to distract the Koopas. What's up with the tiny Marios?
33. After the fight, Yoshi begins eating all the cavepeople's Rock TVs. Um, first of all, the cavepeople didn't have the TVs with them earlier, and second, why did they bring their TVs anyway?
34. Why does Yoshi try to help Bowser out of the mess of blocks? The guy tried to ruinate their isle years ago, and Yoshi's forgotten that?!
35. In "A Little Learning", Peach thinks Oogtar started the roughhousing on the playground. Why doesn’t she suspect that Hip and Hop did it?
Super Mario Bros. are cool like sunglasses!
