Haha, you need to build an automated walk through tort wash. . How often do you usually have to clean their plastrons? I know my leopard and Russian both loves walking over the food and sometimes if they go over the Mazuri, then onto coconut coir or dirt, it's like a little smushed pile stuck too them, specially if it dries before I get to it. Mine are of course much smaller, and easy to lift. Yours, well must be like an island under there if things get stuck
They are great looking torts , but like Mr. Fife said once moving one of those is like moving a big football with a stick . They mostly do what they want not ware you want . But please they are good looking . Good luck
