The Mixing Bowl is an item found in Fatty Bear's Birthday Surprise.
Fatty Bear's Birthday Surprise Edit
Fatty Bear will need the mixing bowl in order to make Kayla's birthday cake. Fatty Bear will find the bowl in either the garden or a kitchen cabinet where the egg beater and (sometimes) other kitchen tools are in. After Fatty Bear enters the kitchen with the mixing bowl, he will automatically place the bowl on the counter.
When used for making the cake, the bowl is used to hold all the necessary ingredients. After Fatty Bear uses the egg beater to mix the ingredients together and pours the batter into a cake pan, Mathilda Rabbit will place the cake pan in the oven for baking.
