Thinner is green and can be used as a solvent to dissolve and destroy foes, buildings and obstacles Wasteland, whether they're good or bad. Thinner is the one of the tools Mickey can use on his quest to become an epic hero.
When using Thinner on other characters, they will get absorbed to the ground. That is, until Mickey uses paint on those characters again.
By using Thinner more often than paint, Mickey will be able to attract Turps. Thinner also replaces water in Wasteland and will hurt Mickey if he touches it. This Thinner replacing the water are called Thinner Seas or Pools of Thinner. At the end of the game, Thinner Pools turn back into clean-fresh water/Paint.
Thinner was one of the elements Mickey accidentally spilled when he was tampering with Yen Sid's desk. With the mix of both Thinner and Paint came the Shadow Blot who defeated Oswald the Lucky Rabbit and took over Wasteland, making it a miserable world for all of the residents after a wave of Thinner splashed down on the residents and lands of Wasteland. Gremlin Gus calls it the "Thinner Disaster ".
Effects on Wasteland and Mickey
- Mickey will look more "Smudged", meaning that more ink will float off of him.
- In Epic Mickey 2: The Power of Two, instead of ink flowing off of his body, Mickey would express a sad face.
- The people in Wasteland will be sad and act negatively towards Mickey.
- Oswald will act meaner to Mickey.
- The music will sound either sadder or more menacing.
- Gus may occasionally call out on Mickey for abusing his usage of Thinner (particularly when he uses it to thin out the residents of Wasteland).
- Your Thinner capacity can regenerate to almost half its total (shy 1/2 a thinner bucket).
- Thinner is strikingly based on Dip, the waste where the antagonist Judge Doom use to melt cartoons in Who Framed Roger Rabbit.
- As a matter of fact, two of the ingredients of dip listed in the film - turpentine, benzene and acetone - are, in fact, used as paint and ink thinners.
- If Mickey fires Thinner at Oswald in Epic Mickey 2: The Power of Two, the latter would take damage, similarly to contact with Thinner-based hazards and attacks.
