From Paper Mario Wiki
Arantula is a deadly and more colorful version of a Pider. It has very high health and attack power. Like a regular Pider, it spits webs at Mario or his partner. Every now and then, it'll shoot out three webs at Mario and his partner in one attack. This attack is a lot harder to dodge since the Arantula shoots out the webs a lot faster, twisting its head in the process. Just one of these possess as a big threat and four could be nearly fatal. The best way to defeat them is to use a powerful item or special attack.
