Test of Observation
This test is done by Krystal, and is the only one that she is featured in. The test involves the first Krazoa Spirit, who goes inside one of the six large, moving vases. They all move around, and after stopping, Krystal must guess which one it is inside. She must avoid being hit by the moving vases which can injure her. Krystal finishes the test after correctly guessing the vase three times.
- On the official, defunct Star Fox Adventures website, there was a flash game called "Krystal's Test of Visual Acuity". It is a clone of concentration, and the player's goal is to correctly guess which of the SharpClaw Crates contains the PukPuk Egg. If the player successfully guessed three times in a row, they are rewarded with a wallpaper of Krystal riding a CloudRunner.
