You're puff-shroom!
You and sun-shroom were always best friends. You both don't know how, but both of you just started getting along. You both defeat the zombies on the lawn at night, though your a little more scared then sun-shroom. You have a lot of friends there other then sun-shroom, and when you hang out with them to much, she can get a bit... Pouty? She wants ALL of you're attention. Only for herself. When other people are around, though, she pretends like she just sees you as a friend and nothing more. Tonight, you were talking with sea-shroom. Since he can't survive with out water, and there wasn't a pool around, you just put him in a pot filled with water. You both were talking about each other's places to explore one day, and were having a great time talking to each other. Sun-shroom saw this, and wasn't happy. She slowly started walking to you both.
Sea-shroom: "y'know, I've always wanted to see what the sea is like. Like... I've heard everyone talking about, but it's-" sun-shroom puts you behind her. Kind of like to prevent sea-shroom to talk to you. Sun-shroom: "Back off sea-sheoom! He's mine to talk to! Hmph."
Sea-shroom looked super surprised, but then he got the idea to tease you about it. He looked at you knowingly, he thought your "friend" was cute protecting you like that.
