All the Dolphins at the center are trained to retrieve trash that has mistakenly fallen in to their pools. Upon seeing a nearby trainer, they are to take said trash to the trainer. In return, they receive a fish for their cleanliness.

However it seems that Kelly has found a loophole in the system, and is exploiting it to interesting ends. She hoards her trash, underneath a rock at the bottom of her pool, and when she sees a trainer she goes down and removes a piece of paper or trash to get her fish.

However she won’t use all her paper at once, instead she holds on to them for the future. It is an interesting behavior, considering that it is very much like humans storing food for the winter; it displays an awareness of tomorrow.

Dolphins have long been observed to take great care and exhibit much intelligence in their day to day lives. Scientists have observed a dolphin using the spiny body of a dead scorpion fish to extricate a moray eel out of a crevice.
