In the sand
You can not cheat to get sand dollars. You have to work for it, or you have to buy it.
Sand dollars actually live on the bottom of the ocean or under the ocean floor. They can move throughout the sediment. The have things called Podias which move the sand dollar's food towards its food opening. They have few natural predators, some of them are ocean pouts and sunflower starfish. You will commonly find them broken mostly because of the undertow and the tides. Sometimes you will find a sand dollar and it will most likely be a dead one.
Sand dollars grow and develop their unique skeletal structure through a process called biomineralization. They absorb calcium carbonate from the ocean water and use it to build their hard, flat skeletons. As they grow, the sand dollars' skeletons develop distinctive patterns of pores and spines, which help them move and protect themselves.

what is the sand dollars kingdom
Because they are like any other sea creature (espically starfish) they are living with small polyps that cling on to things and then pull themselves wherever they want to go. The sand dollars then die and leave a skeleton that people use as decorations.
