Mulch-O-Matic is one of the 14 Custom Contraption players that can build in the Workshop as part of the Science Theme on Two Point Museum.
Custom Contraptions like Douse-N-Dose, Mulch-O-Matic, Sprinkler Pump, and Robo Charge-Master have additional effects that help your museum become more efficient.
The Science Experts use blueprints discovered in Bungle Labs and recources from expeditions to craft these high-tech devices.
Use Mulch-O-Matic To Produce Mulch
While most crafting materials for the Workshop can be obtained by sending Janitors on Expeditions into Bungle Labs, Mulch is the one key ingredient that cannot be found through expeditions alone.
This essential resource is crucial for creating advanced Contraptions and valuable Cargo.
To produce Mulch, the museum needs to place the Botany Exhibit in a Mulch-o-matic, a device that converts botanical exhibits into Mulch. This device is indispensable for efficient Workshop operations.

Even if you don’t plan on building many Custom Contraptions, Mulch remains essential for crafting Illness Elixirs, which prevent sickness among your staff and visitors.
For a source of Mulch, send an Expert with a First Air Kit and Survival Skills to the Allotment Labs.
With the right equipment and personnel, you will bring back a supply of this back a Sickly Pear after a relatively short trip, making for an easy batch of Mulch.
