Product Description

Whoops, watch where you sit down. Sometimes weirdos put whoopee cushions on the seats. 

This official UNDERTALE mug was designed by Audrey Waner to hold 8 oz. of ketchup (or tea). Each one comes with a bonus coaster.

Microwave safe. Hand washing recommended.

Also Available On

Our custom-made mugs are heavy duty, but if you want them to last a long time you may consider washing them by hand and avoid microwaving. This is especially important for our color-changing mugs, as exposure to constant high heat can remove the color changing ink much faster.
