This skip was inspired by a real person, the uncle of a friend of mine who owned a plot of land in Florida where he raised banana spiders (the giant golden silk orb-weaver variety, not the brown ones that kill banana farmers in South America).
Edit: Dexanote informed me that there is an episode of Futurama with a roughly analogous plot in which Fry gains regeneration through super-smart worms or something. This was not intended to be similar to that in any way, but rather a story of a nice old lady who care for spiders, and one day the spider mother goddess decided to repay her kindness.
