**Title:** Breaking All 320 Bones as a Dog (in a game)
**Summary:**
* The creator plays as a dog in a game (likely GTA V, given mentions of Maze Bank and Mount Chiliad) with the goal of breaking all 320 of the dog's bones.
* Various attempts are made to achieve this, including:
+ Jumping off buildings and structures
+ Getting hit by cars
+ Snowboarding into crashes
+ Dropping large objects (bus, tugboat, yacht) on the dog's head
+ Using a shredder
+ Navigating an obstacle course
* After numerous failed attempts and glitches, the creator finally succeeds in breaking all 320 bones after approximately an hour of trying, with the final few bones broken on an obstacle course.
* The video ends with a call to subscribe, like, and check out new merchandise.
