Hippos in the mud cake

I made this in hurry, for a surprising birthday party!

It was my housemate's belated birthday.

I simply used a store-bought plain chocolate fudge cake. 

It was only £1.49.

I made the cake board out of its box and aluminium foil.

I used Kinder Happy Hippo.

It was only £1.00 at Poundland.

There were five hippos in it.

I only used two.

See my Ducks in the Mud Cake too,
which I made last year for my housemate.
