This potion is made by using the Spider + Pool Noodle in the cauldron. You can stack these to increase the effects of it.
This potion makes you turn into a human centipede. You will grow a bunch of new body sections & walk around like a long bug on the ground.
The more centipede potions that you stack together before brewing, the more centipede pieces you will grow. You can stack these so high that it turns you into a massive bug.
This is definitely one of the most fun potions to use in Wacky Wizards.
This Potion is spell number #27 in the potions book.
