"Open the Chute, Squirty!"

Both Grammy and her dog Squirty both fall to their deaths after Tom accidentally makes a hole on their car's balloon with a harpoon while aiming at Jerry, causing them to try to jump with a parachute, only to realize that the backpack they took had none mid-fall, causing them to fight while falling straight to Borneo and their dooms.
