It's alive (and what's your next deduction sherlock!)

ooc-- just to freak everyone out my mate Katie had a dream about the pink tree. But I do keep her up to date on what's going on
------------------------------------------------------------------------------

Location:- medi-bay
People:- Phil, Tara, Keto, Pink Tree, Wildflower, Marco,
Tara woke up in the medi-bay. Phil was sitting next to her on one of the standard chairs. Tara tried to move then worked out that she had been stunned in the back and was temporarily paralysed from the waist down.
"Ow smeg" she croaked. Phil turned at the sudden noise and smiled when he noticed she was awake
"Welcome back to the world of the living...." he paused "God that was ironic" Tara laughed and said
"Does this mean i'm forgiven?" Tara said with a sad puppy look on her face
"I suppose so yea" "What the hell is that!?" said Tara pointing to The appendix in the size 14 observation jar. The affects of the stun wearing off she got to he feet rather nervous of crumpling in a small heap, and walked over to the jar. Keto was in a frenzy about all the toy money spread in the main medi-bay,
"Clean it up! what if an emergency case comes in!" Keto yelled
"Does she count as an emergency case" Wildflower countered. The tree rustled
"She already has a boyfriend you stupid pile of wood chippings" said Keto. The tree look saddened
"Hey, he didn't mean it pinkie" consoled Tara. The tree rustled happily again and Keto grumped angrily and stormed off into his office. Tara continued to the jar with the appendix in and unscrewed the lid. It jumped out and barked at her with joy and started bouncing about her legs like a small puppy,
"Awww, your so sweet" Tara cooed and walked into the room where Phil was
"What on god's earth is that!" he panicked slightly and backed up against a wall  thinking it was dangerous
"It's only a sentient appendix. It's sweet don't you think? Do you think I will be able to keep it as a pet?" .....
