Say Cheese! Achievement
Scan a Grumpus after saucing them with cheese.Considering you can not use your traps while in the village there are limited options you can get this achievement.
Cheese sauce is obtained in Sizzlin' Sands. It's located high up but you can use your snackgrappler to grab the cheese.
Once you have cheese you can drop some on Shelda and get the achievement.
The only other Grumpus you will have access to cheesing is Eggabell in Frosted Peak. She never returns to the village so she is always out there.
