Spiky's jacket were all dirty, and the weather is so cold, so he really need a jacket to wear.
The only thing running inside his head is to look for Pinky, and ask if he can borrow one of her jackets. Without hesitation Pinky gave one jacket to Spiky, but with one condition which is to take care of it.
Spiky promised and immediately wear the jacket.
The next day, Spiky was removing the jacket to return it to Pinky. Then suddenly, its zipper got broken and stuck. Spiky can't remove and get out of the jacket for one day.
I came up with this scenario because this thing always happen to me when I wear a jacket, but I have not experience being stuck for it the whole day.
