Wario Land 3

Before he can say "I hate Mario", the box pulls him inside and into a room with a dark figure, who strikes a deal with him.

Find all of the missing Music boxes and he can leave.

And any treasure he finds he can keep.

Much like Wario Land 2, Wario can't die from any attacks by the enemy.

However he can change form after certain attacks, which can both help and halt his progress in each level.

New forms of Wario include Invisible Wario and Ball of Yarn Wario (an un-controllable ball of yarn, with Wario inside).

Also, basic attacks such as swimming and the butt stomp don't become available to Wario until after completing a certain amount of levels, meaning you have to go back to completed levels to access other areas full of loot.

Wario Land 3 for Game Boy Color is currently worth €33.92 loose, €70.62 complete in box, and €139.06 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

Wario Land 3 has a steady sales history on the tracked marketplaces, meaning it trades hands regularly and isn't considered particularly rare.

Loose means cartridge or disc only, CIB (complete in box) includes the original box and manual, and sealed means factory-sealed and never opened. For Wario Land 3, loose is €33.92 and CIB is €70.62 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.

The PAL version of Wario Land 3 is currently worth €33.92 loose, versus €29.78 for NTSC-U. Regional price differences usually come down to print run size and regional collector demand.
