This fruit tart rocks

It was our friend Daryl's birthday, so Kenneth went down to Chinatown to buy him a crazy cake from the same place that made the puffer fish a few entries ago (it was a bright pink pig this time). It was mother's day, so they gave Kenneth a free gift in a red box with a picture of a fruit tart on the front.

The happy fool rushed home, holding the box carefully to avoid smashing the tart, and when he got home he quickly put it in the fridge. When we decided to eat the tart after lunch, we took it out and we realized that it was no tart. It was a piece of rock with a picture on it. It's like a decorative stone, and very inedible. We were very disappointed.
