User blog comment:Bobdave/Maractus vs Cacturne. Rap Battles of the Pokédex Season 1/@comment-25701332-20150528155720/@comment-4490782-20150528155935

Maractus is based off a prickly pear cactus and and Cacturne is based off a saguaro, which is scientifically called carnegiea gigantea, named after Andrew Carnegie. Therefore pear vs Carnegie. Obscure hint, indeed. The one I posted in this one might be less obscure.
