You fell into the Underground. There were torn up Golden flowers below you.

You got up and rubbed your head. It hurt from the fall

A living Golden Flower popped up from the ground.

“H-howdy!.. I’m Flowey! Flowey the Flower…. you’re.. new to the Underground.. aren’t you?”

The Flower sighed

Flowey: “Humans.. don’t survive here.. It’s not safe here.. It’s always.. Kill or Be Killed down here. Monsters don’t show mercy. But that’s okay. I’ll protect you. What’s your name?”
