The four questions ask "why is this night different from the others?" That is because on Pesach we do a lot that we do not do on other occassions.

Imagine an entire country of people with sentient toys mixed in with them. You may be asking why sentient toys are a part of normal human society, but there is a fairly simple answer. A small child with the ability to turn people into toys by touching them and have all memory of their existed erased from existence.

When the child that has these abilities is knocked unconsious, all the toys are returned to being human and after years are able to reunite with their friends and families.
