The Bubble Blade is wielded by Bubblez. It does the same amount of damage a Diamond Sword would do. Unlike the Diamond Sword, this blade can blow bubbles. The bubbles that are blown out of it can be manipulated by Bubblez to do as he pleases.

MacGuffin
The MacGuffin is a crown that can be worn to grant power. CW's primary goal is to acquire this crown; thus, he recruits Bubblez to help him find this object. CW seems to know what it can do, but Bubblez never learned its purpose past than the fact that it gives a kind of power.

Fish Wings
The Fish Wings are used by Bubblez. Their practicality underwater is low, for when you're submerged, you generally don't need to fly.
