The Bunny Wabbit Backpack is the smallest of the backpacks used to increase a character's storage capacity. A Level 5 Fitness character can carry up to 85 lbs with the Bunny Wabbit Backpack equipped.
A Bunny Wabbit Backpack can be acquired from a house in Dejado, which can help with the early game. The player will be prompted to find this backpack if they have not done so already at the start of the Home Improvement Quest.
When increasing a Fitness level, either by levelling up or using Health and Fitness Guides, the carrying capacity will increase by 7 lbs. This is because increasing a Fitness level adds 2 lbs to a character's personal carrying capacity, as well as the 5 lbs per level provided by the Bunny Wabbit Backpack.
