LABATORY YPENBURG – The lab consists of a sandpit measuring 30x15 meter, a cabin, a large sea container and lots willow trees. There is the bone yard as well. Usually there are only one or two animals living at one time. As soon as the development of an animal is at its end, I declare it extinct and I push it onto the bone yard. The animals there can be seen as the fossils of extinct species. Exposure to sun and rain causes the tubes to fade, making these appear more bonelike with time. The sandpit is the pre-heaven for the beach animals. They are not yet ready to survive the real beach. I still have to train them. Usually I take them out once a year to the real beach to let them get a taste of their natural environment.
