Rick had taken a much larger dose of the pink mist then Rick had and so when Brendan peeked quickly inside all the teen saw was still shifting and growing dragon body and coils.
He quickly slammed the door shut and waited a half hour
figuring by now the creature must have turned back into his
loveable stepdad.
However when he opened the door even more of the pink fumes billowed out and the unblinking red serpentine eyes
and the first spurts of fire were coming out of the things
nostrils.
As Brendan quickly slammed the door shut again he heard the distinct creak of floorboards straining under the weight of something
immense and still getting heavier
in that bedroom.
Clearly he wasn't going to be returning to his bedroom tonight
if ever.
So he gathered some clothes from downstairs
and phoned his mom telling her not to come back to the house
tonight as Rick was feeling pretty rotten at the moment because
of another failed experiment.
As Brendan was exiting the from door he heard the sounds
of the houses inner walls bursting and the dragons tail slid down the stairs at the same time Rick made what sounded to Brendan ( he hoped ) a unhappy growl.
Clearly Rick was finally realizing this time he had succeeded
all too well.
Like they say "Be careful what you wish for or you might get it "
