Item boxes (monitors) are scattered throughout each act and contain various power-ups that provide temporary advantages. Hitting an item box with a jump or Spin Attack will activate its effect.

- Rings: Grants 10 rings. Essential for maintaining your ring count and protecting yourself from damage. Always prioritize collecting these.
- Invincibility: Grants temporary invincibility, making you immune to all damage for a short period. Use this to rush through dangerous sections or attack bosses without fear.
- Speed Shoes: Significantly increases your character's speed for a limited time. Great for breaking speed records or bypassing tricky platforming.
- Shield: Provides a single hit of protection. If you take damage, the shield absorbs the hit instead of you losing all your rings. The shield breaks after one hit.
- Elemental Shields (Fire, Water, Electric): These shields offer the same protection as a regular shield but also grant additional abilities:
- Fire Shield: Protects from fire-based attacks and allows for a mid-air dash.
- Water Shield: Protects from drowning and allows for a bounce jump on water surfaces.
- Electric Shield: Attracts nearby rings and allows for a double jump.
- Extra Life: Grants an additional life, preventing a Game Over if you run out of rings. Always a valuable find.
- Super Ring: Grants 50 rings, a substantial boost to your ring count.
Always be on the lookout for item boxes, as their contents can turn the tide of a challenging section or boss fight. Prioritize elemental shields for their added utility.
