Stealing is wrong if the owner of the property sees you do it - we need to make a trade with Monosyllabic Max to take his helium.

You can find out yourself by asking him, or clicking the signpost to reveal his exact quote.

Do you remember the end of Chapter 2? Where we dug up the robot's torso?

Well, the hole we dug that torso out of was FULL of worms! Grab a handful!

Dexter apparently agrees, and needs "a can or something to put them in". What a wuss.

This is another one of the game's obscure solutions - for a nudge in the right direction, try exploring the forest.

The area that the Space Scouts are trying to find.

From a starting point of the forest entrance, follow this path:

Right (To the forest) Up (To the forest field) Right (To forest) Left (To waterfall)

We need to get to the bottom of the waterfall by crossing the slippery log.

You need to cover the slippery moss with something that can be safely walked on.

Something rectangle-shaped and long, that can be (and is) curled up for easy storage.

You may have grimaced when you first saw it in the previous chapter.

Uncle Jedo's yoga mat in the Bodega's attic - it can be laid on the slippery moss to make it easy to cross.

At the bottom of the waterfall, you'll find an empty can among the garbage.

Like I said, obscure solution, but we now have a way to hold the worms!

Giving Max the can of worms makes the deal finalised, and you now have a canister of helium!

If you're not sure what to do with it, follow these hints.
