Listen to this Spooky Druid's wisdom. But beware, for this wisdom is cursed! Once you know it, you will never be able to unknow it! Even when you think you've forgotten it, it will still be there, indelibly etched onto the very meat of your brain, just awaiting the proper stimulus to rise again! I mean, that has nothing to do with this particular wisdom, that's just how the neurology of memory works.
Imagine an infinite number of alternate dimensions, sliced thin like salami and all layered together in a delicious sandwich of universes. In these parallel strata of time and space, the Squishables are very, very different.
