Fish tank cake

Today my dad is sixty* so I baked him a cake yesterday. A piñata cake, but like a fish tank or under the sea or in a pond- so blue on the outside and then inside filled with fish and sea creature sweets. My dad has tropical and outdoor fish so it seemed an appropriate cake to make. The cake was meant to be blue too but it didn't quite dye like I planned. Still I'm chuffed at how it turned out! Happy birthday dad!

*he is excited to be able to use his new bus pass and go on a trip tomorrow!
