The spider probe is a robotic walker with a camera attached to monitor where the two probes, Leo and Ike can't go.
The spider probes come equipped on each probe, and walk on six legs over terrain. They can be used to see underneath certain things or explore to search for threats. each one has a camera on its top side.
In the MovieEdit
The spider probes were not used much, only to explore certain points. Ike used one of these to explore a certain type of mushroom structure, where it accidentally completed a circut and its circuts were shorted out. Each probe came with two spiders.
