RC Shroober

An RC Shroober is a light blue Shroob with purple spots that has a pair of radio antennae attached to its head. Using its antennae, an RC Shroober can control electronic devices that use radio waves. During the Shroob invasion of the Mushroom Kingdom, RC Shroobers were placed in command of the egg factory inside Yoob's stomach. As such, RC Shroobers were presumably in charge of converting normal Yoshis into additional Yoobs. RC Shroobers also took pleasure in terrorizing the captured Yoshis inside Yoob's stomach. Thankfully, Mario, Luigi, Baby Mario, and Baby Luigi shut down the egg operation and freed all the Yoshis imprisoned by the RC Shroobers.

In battle, an RC Shroober summons radio-controlled weapons with its antenna. First, an RC Shroober may summon a radio-controlled UFO. This flying saucer would hover over a Mario brother and beam him up, causing damage. To counter this attack, Baby Mario and Baby Luigi had to use their Hammers to knock the UFO down as their older counterparts were being beamed up, sending the flying saucer crashing into the RC Shroober.

RC Shroobers can also summon a radio-controlled mobile bomb. When summoned, this bomb would circle around the brothers, attempting to hit Mario and Luigi and explode. The two brothers could dodge this attack by jumping. Eventually, the mobile bomb would explode on its own without hurting anyone. Additionally, if an RC Shroober jumps before summoning a mobile bomb, the little explosive will stall before starting on its circular path. Also, the direction the RC Shroober's antennae point before the attack indicates which Mario brother the robotic explosive will attempt to attack first.
