Jeff thought it would be funnier if they could still talk as if nothing happened, so he wrote it down into the file. The more they would eat the grass, the more they would personally enjoy braying.

Slowly, their mind will become more stubborn, more like a donkey, but will still retain some normal human behaviour. If whoever Jeff chooses to change needs to be washed, they will walk up to wherever they could find another donkey and allow themselves to be licked as they will lick the donkey to groom it.
