Take "S" out of spider and you'll get this. Pider is a arachnid creature found in the Great Tree. Like all spiders, Piders spit out webs. Usually they spit only one web, but they can spit three webs at both Mario and his partner. Piders can only move their legs and head; they can't move their body unless they're on their web going up and down. Piders also have a more colorful, more powerful relative named Arantula.
