Gooieduck are edible objects usually found in Subterrarean. They hang from ceilings, suspended by thread-like roots, and are light blue in color. They can also be found being held by Scavengers in Farm Arrays, which can be traded, worth 2 in value.
You must not eat it, instead, hold it until you find Worm Grass.
(You'll only need one Gooieduck to do this, using 2 is optional)

After finding Worm Grass, you must crouch while holding the Gooieduck to aproach it, otherwise the effect of the Gooieduck won't apply and you'll eventually die.

Aproach the Worm Grass and that's it! Now you're touching grass!



But be careful, the moment you stop crouching the Gooieduck effect will stop working. This is important to know if you need to turn around or try to climb a corner while being in the Worm Grass.
