Always keep an extra power-up in your inventory (by pressing 'L' or 'R' to swap). This allows you to quickly recover from a hit or switch to a more suitable power-up for an upcoming challenge. In Bowser's Fury, collecting power-ups is even more crucial due to the open world and Fury Bowser's unpredictable attacks. Don't be afraid to use a power-up if it helps you secure a Cat Shine or survive an encounter.
This inventory system functions similarly to the item storage in Mario Kart DS, where holding a reserve power-up provides a strategic advantage during high-pressure encounters.
While Super Mario 3D World allows players to bank a single reserve item, Mario Kart Tour expands this inventory system by offering up to three slots based on the character.
