Straight ahead, the Dark Forest (male)

You travel through the Dark Forest. You look at the darkened trees; their trunks are twisted together, and their bark is blackened. The sunlight is scarce, swallowed by the canopy above, and after a few hours, you find a glade with a pond, however, you listen to a noise, something is close to you... You draw your sword; this creature will not surprise you.

A big slime tries to swallow your body, but you are prepared; you pierce it with your sword and the slime explodes.
It's destroyed, but you are covered in purple slime.
The acids hurt your skin, but you can endure it; it's not poisonous.

You can continue to travel to the Mountains of Ash, or you can clean your body in the pond.

What do you do?
