DIY Potato Tortoise Cake

Make a potato-based birthday cake for your tortoise! Skin and chop potatoes, then boil the potatoes until soft. Mash the potatoes and mix with the calcium carbonate. Stir some food coloring into the mixture if desired, or mix in any other finely chopped treats your tortoise might enjoy. Form the mixture into a cake shape and stick chopped carrots into the top of the cake in place of candles.

Ingredients: potatoes, calcium carbonate, food coloring, and carrots
