A Spider is a common neutral "mob" (from mobile) that has the unique ability to climb walls. They appear in the videogame Minecraft. Spiders are hostile to the player and to iron golems. Spiders can climb up over walls and other obstacles. If a spider cannot find an ideal path to the player (when a player goes behind or on top of a wall), it will get as close as it can to the player's position from the outside or below, and proceed to climb the wall vertically until it gets to the top.
The Hot Wheels version of this "mob" is quite literally a spider-based vehicle. It is one of the rare vehicles with eight wheels (which represent the spider's eight legs), see which vehicles this spider joins in the See also section. This spiders has a secret: it has an unfoldable ramp.
