Map: Tranquility Falls / Level: Draggin' On
You must finish the level "Draggin' On" without destroying a single crate. You can press L2/LT to check the crate count. It must be 0/139 until the end of the level. This means you cannot destroy any Checkpoint Crates either! The lack of checkpoints is what makes this hard.
Here are some tips:
- When you get the purple spin ability, use slide-jumps before activating it to gain more height. Using this trick is mandatory in some sections. You have to slide-jump and then activate the purple spin in some sections.
- Halfway through the level use the Bonus Path ("?" Platform). This creates a checkpoint without destroying a crate. When you are brought to the bonus area just drop off the ledge to respawn outside.
- If you destroy a crate just get yourself killed to respawn at last checkpoint. No need to restart level.
- Try not to defeat any enemies. They might fly into some crates uncontrollably. Better not take that risk.
The Blue Sapphire Gem will be in front of the level exit when you reach it without destroying a single crate in this level.
Be sure to step into the level exit afterward, the Sapphire-er Acquirer trophy / achievement unlocks after the level.
