guppy microwave heating pad



​FishBellies are hot-or-cold healing

packs filled with extra-clean, non-popping, large-kernel corn. To ensure your safety and help your FishBellie last for years to come, please follow our instructions carefully!


For cold therapy, simply place your FishBellie in the freezer for 1-2 hours. When freezing your FishBellies, place them in a plastic bag to protect them from food odors.


For heating pad therapy, warm up your Big and Little FishBellies in the microwave for 1-2 minutes, adding 30-second intervals as needed. Guppies only need 30 seconds! 

Only heat FishBellies in standard size microwaves WITH A TURNTABLE. This ensures that heat is distributed evenly, preventing damage or hot spots on your FishBellie. Be sure to FOLD THE TAIL UNDER YOUR FISHBELLIE as it heats up, so that the turntable can rotate freely. Do not put FishBellies in mini,

or college dorm microwaves.

Never leave your FishBellie in the microwave unattended. 

Be extra-careful the first time you heat up your FishBellie, as every microwave is a little different. We suggest massaging your FishBellie a bit halfway through heating to ensure that warmth

is distributed evenly.


Use Caution


FishBellies are great for kid boo-boos, but only for children ages 6 and up. FishBellies are not for babies! Adult supervision is always required.

Do not use FishBellies on numb body parts, as this can cause serious injury. 

Do not store in extreme heat or humidity,

as natural corn contents could spoil. 

DO NOT put FishBellies in the oven!

More detailed instructions are included with each order.
