In the meantime here is the the latest product from the disturbed mind UU inc
Invention Name:Port O privy ™
Invention description:A small wooden booth containing a seat with a hole in,this unit rests on a sapient pearwood platform creating a privy on legs.These constructs can then be herded to wherever portable toiletry solutions are needed,for example music with rocks in concerts or other outdoor events.With proper training these privys will know to run off and empty themselves when they are full.A dirty job but someone has to do it.
Notes:Do not annoy the Port O privy ™ during use,you may find it locks the door on you and runs away with you inside.Always wash your hands using the small basin and pump provided,they don't work but you can have fun trying.Use of the Port O privy ™ is free for event guests as the cost of sapient pearwood is covered by the Port O privy ™'s ruinous rental price.
Please note that during the first roll out of this product a small group of them broke away and are now renting themselves out with no human input whatsover,if you see one of these rogue privy tribes please return them to Port O privy ™ HQ
