| # | Step-by-Step Objectives |
|---|---|
| 1 | Optical Disk A (Toxic Anthill Optical Disk) is hidden deep in the Toxic Anthill. We recommend equipping Sizzle-reduction armor and bringing Mintito Smoothies, as you may have to fight the Cockroach Queen in order to get Toxic Anthill Optical Disk. |
| 2 | ![]() When you're ready, head to the northwest part of the map, south of the Picnic Table. Look for a green spray can near the roots of a toppled tree, which marks the south entrance to the Toxic Anthill. |
| 3 | ![]() After entering the tunnel, keep heading straight until you reach an intersection. Take the left path. |
| 4 | ![]() At the end of this path, you'll see a green can submerged in nasty water. Drop down the ledge, then turn to the right. |
| 5 | ![]() Keep heading north. You'll encounter a giant cockroach along the way, but don't worry, this isn't the Queen. Just continue forward, and you'll soon reach an area where the path is completely surrounded by nasty water. |
| 6 | ![]() Parts of the road in this area is cut off. Jump to the other side to avoid the Nasty Water, as it will drain your Health. |
| 7 | ![]() After reaching the end of the walkway, grab the Raw Science to the right. |
| 8 | ![]() Continue heading north. You will soon arrive at the entrance to the large arena where the Cockroach Queen resides. Be ready for a boss fight. She will go aggro once she sees you! |
| 9 | ![]() Once the arena is clear, you should find Optical Disk A next to a corpse near the two mushrooms blocking an alcove, which also contains the unique weapon, Gloom Skewer. |
After obtaining Optical Disk A, load it into a Ranger Station to unlock new crafting recipes, which can be purchased in the Science Shop using Raw Science (RS).
