Didn't quite get this, but it's about a new type of yukkuris that were somehow created when trying to prevent yukkuris from getting hurt during shipping. Their paste cores are strengthened, so they can take more mental stress, and their skin is extremely stretchy and durable. Anon has a Marisa, a Komarisa and a Koreimu, and keeps hitting, throwing, slapping them around, and if they get injured, all it takes is some orange juice.
