A Smash Box can be stomped on by Croc to reveal a certain item. They appear as a cube shape with ? symbols around it, and look different depending on the level. They can only be tail-attacked while underwater. They can contain the following:
- White Crystals (ranging from 5/10)
- Coloured Crystals
- Spinning Gear (The Tower of Power only)
- If Croc has died during a level after opening a Smash Box with a Gobbo, Coloured Crystal, or Heart, the box will respawn, but if opened, it will contain butterflies, which are non-interactive elements.
'Smash And See' Boxes
This type of box has nothing in them and only appears in the level Smash and See and is used to stomp on to defeat a spiky Dantini also unique to this level. They will walk across a line of this type of box and will fall into the bottomless pit when Croc removes a box. This is the only way to defeat these type of Dantini and is used to get a gold Key to open a Locked Door.
This type of box only appears in the level The Tower of Power, and is found in a stack of four. Croc must attempt to push them in order to make steps to climb up, but they cannot be opened. If Croc accidentally causes them to fall on him, he will lose a life. There is a Red Button which will reset the stack to how it was if desired.
