Something was wrong.
Frisk had fallen down this hole on countless RESETs, but it had always been exactly the same.
This clearly wasn't leading to the Underground, though, and where it did go wasn't even in a format that allowed them three-dimensional movement.
Something appeared on another layer.
Layers. That was a concept they'd have to get used to.
It was difficult to make out, since it was mirrored, but they managed to read... "Hydrocity"?
And this time their fall was broken by the water. An altogether more welcoming land than the flowerbed of the Underground, they decided.
Still hurt, though.
