I used to have a speed bag once too. It got deflated but not in the same way as what happens to Fluff Pup!

Panel 1: Fluff Pup, a brown puppy with a yellow crown and fuzzy ears, faces a gray speed bag that hangs from the ceiling. She has a look of determination on her face and has her front paws in a pair of red boxing gloves. Her paws are up in preparation to punch.
Panel 2: Fluff Pup has her eyes tightly shut as she quickly and furiously pummels the speed bag, which shakes back and forth as she punches. Her crown bounces on her head as she punches!
Panel 3: The speed bag has suddenly burst open with its most recent swing. Fluff Pup, with a giant exclamation point and her eyes giant, is immensely surprised to find piles of CANDY falling out of the busted speed bag. Lollipops, chocolate bars, gumballs and more tumble to the ground!
Panel 4: The deflated speed bag has stopped swinging. Fluff Pup rubs the back of her head in confusion. She watches Pug Pup, a pug puppy with a purple cape and a red-and-gold crown and Corgi Pup, a corgi puppy with a multi-colored tiara, stuff and munch the fallen candy into their happy mouths. They have appeared suddenly out of nowhere because they love candy!
