The Pro-Firefly was a custom design sold only at Dave's Skill Toys online store. The artwork was designed by Scarecrow, Matt Carter. Matt used artwork that was previously used as a web graphic at skilltoys.com and created this unusual sidecap design. This yo-yo carried the web address of yoyodave.com, because this was a hybrid product, not made completely by Playmaxx. The yo-yo is a Pro-fire GT and the sidecaps were made by Playmaxx as well. A bee bearing was installed rather than the standard brass transaxle. The light kits were made by Spintastics for their light up yo-yos, including the Firefly. Hence the name of the hybrid, Pro-fire + Firefly, for "Pro-Firefly". The lightup kits were each installed by the staff at skilltoys.com, creating an unusual and high performance lightup. Only about 30 of these were made.
