This layout scored me $436 on the final level. I'm interested if anybody can score higher and what their designs are.
Note: you do have to force the poo into the liquidizer at least 3 times after you start the machine.
$544 with this layout. First poo was used for the dog's legs, 2nd went into the liquidizer, 3rd to head, and so on.
I tried to leave enough space between molding, painting, and joining so that I never ran out of liquid or needed to manually toggle any alternators after feeding the dog. Using 1 less joiner means you don't need the extra tank which will save a good bit cash.
