Headscratchers / Super Mario World 2: Yoshi's Island

• Why is losing Mario a game over if Kamek is taking Mario to the castle and Yoshi's going there to save Luigi regardless?
  • Enemies and environmental danger.
• If a boss fight takes place in Prince Froggy's stomach, how come you die if on a later level, you get eaten by a Lunge Fish?
  • Maybe Kamek (who made Yoshi shrink in the first place) made it so Yoshi would live, and be alive while Prince Froggy was digesting him.
  • Frogs do not chew their food, so Yoshi survives being eaten.
• Just where is World 6 anyways? And why does Yoshi need to climb to the top of the island to get there?
  • Several options:
    • Hell, or a hell archetype: It's a wasteland full of dead or evil things where it's always night.
    • A completely unrelated island: Kamek told Yoshi he would never reach the Koopa kingdom, so there's that.
    • An alternate version of the main island: an evil version obviously.
  • The top of Yoshi's island is probably the only place he could teleport from. If the island really is another world rather than just a different island, then it could outright be the only way to get in. Which would also explain why Kamek had a castle built there.
  • The crater of the island's volcano? It is a solitary island in the tropics after all.
• Why does the boss of the first fortress you come to (World 1-4 I think) fly around the room expelling air after you defeat him? Was he holding in a massive fart for the whole battle?
  • The boss is a balloon-like enemy, and when you kill him he punctures.
• This is most jarring in the last level... Kamek spent literally all game long trying to get Baby Mario from Yoshi. Now, in the first part of the level, Yoshi turns into a helicopter to fly into the castle (and leaving Baby Mario in a bubble where he picked up the powerup) while Kamek chases him. The Toadies can pluck Baby Mario while he is in his bubble crying, as shown whenever you let the countdown reach 0. So here is the question: Why then, is Kamek trying to swoop at the helicopter Yoshi flying towards Bowser's Castle, when he can just take Baby Mario directly from the bubble, and just leave and finish his job?
  • Likely because Kamek wants to make sure Yoshi's dead so he can take the baby without Yoshi in the way.
