Chao from Yūyūki

If you free the same animal friend as you're already riding, the sack will instead contain Gooey, who will refill your health. Infrequently, you will find a secret female Gooey called Blob who rewards you with an extra life.

In the original Japanese version, Blob's role is filled by Chao, the female protagonist from Yūyūki.

Sound Test

When you unlock the Sound Test, there is an image of Kirby, Rick, Kine and Coo sat around a table, while Gooey and Blob are in the background playing a piano.

In the Japanese version, it is Chao from Yūyūki who appears playing the piano, recreating the ship's lounge scene from her game.
