| other foods to see what my little slime mold would be willing to
| eat. Carby things like pieces of bread, etc. The funny thing is
| that it seemed to really like those other foods, even multiple
| feedings in a row, but would then spontaneously refuse to respond
| to those same foods again. I've heard some anecdotes suggesting
| I'm not the only one to witness this. It really does seem like
| the slime mold is "remembering" at a level that may go beyond
| slime trails.
