Friend

Friend (in this concept) is a adorable sheep and had his owner literally DIE because a child thought it was a good idea to let a blue obsessed ghost (the sheep's owner) visit a green screen man. Friend is kind, cute, blue, and loving! Also "friend" (in other concepts) also means someone who you can get mad at but remember you had something to tell them, they keep your secrets, talk to you when you're feeling down, they can literally save your own life!

"friend is such a cute sheep!"
"I know right!"

"ugh you're so annoying!"
"wait but I need to tell you something, don't you think the teacher is being weird?"
"yeah she kinda is"
