Q25: Why did the pirates capture Carmen the whale?

For her blubber.

I'll accept, although an explanation of why they needed it would have been more suitable.

Q29: In Rayman Revolution, where does Rayman fight Foutch?

The Lava Sanctuary.

That's not quite what I'm looking for

I thought you meant the level. Well, I'll just for the next one then!

In the Lava Sanctuary, precisely in a closed area with lava everywhere, with a circular structure with some arcs that contain stalactites.

Ahem, BENEATH the sanctuary of rock and lava.

Beneath the Lava Sanctuary?

In The Lava Sanctuary and Ray-Type Challenge

It's definitely in the Lava Sanctuary (not beneath - those names are switched in the PS2 version) in the area Haruka described.
If you want to know where it's located, you can access it from a cave in/connected to the Pirate Factory. Or from the Rainbow Creek stone circle.

why everyone forget the ray-type game?
