Squatt was a servant of Lord Zedd and Rita Repulsa, the dimwitted sidekick of Baboo. Squatt was a short, blue-skinned troll with a large horn. He wore metal armor.
Squatt was rather excitable, and may act like an eager child when Rita had a plan, or when the Rangers were having trouble in a battle. Squatt was easily frightened by his bosses' bad tempers. Squatt was a coward and, rather than fight, he along with Baboo, would accompany Goldar, Scorpina and monsters as they attacked the Earth and cheer them on. However, he often went to Earth when there was no fight going on because his main duties were acting as a spy and saboteur, as shown in episodes like "Switching Places", "Foul Play in the Sky", "Calamity Kimberly" and "Rita's Seed of Evil".
Squatt later left the moon with Zedd and Rita when they fled from the Machine Empire. He was seen in "Countdown to Destruction" among Rita and Zedd's forces but wasn't shown when Zordon's Energy Wave struck so whether he was purified or destroyed is unknown.
Squatt's birthplace was given as Myrgo, Venus. This is confirmed in the comic Saban's Go Go Power Rangers #6.
In Saban's Go Go Power Rangers #6, Squatt's origin is revealed. He was given to Rita as a newly born baby, as an offering by his parents in an attempt to have Rita spare their lives. Unimpressed, Rita decided to keep the baby but killed Squatt's parents remorselessly. She even said to the baby "you're a squatt little thing, aren't you?". Thus, it's revealed that she raised him like her own son.
Squatt's hobbies included collected slugs and maggots which pickled in his leather pouch to eat for lunch.
Squatt was described (in this and numerous sources) as "half warthog, half blueberry," with "a brain the size of a peach pit."
Rita only kept Squatt around because he loved to fight (which is ironic since he was never actually shown fighting throughout all his appearances).
Squatt's dials constantly monitored the gasses in the air, but he would forget to monitor the dials; overexposure to oxygen caused horns to sprout all over his body and his brain to burst through his helmet.
Despite having some wearing goggles on his helmet, he is never seen using them in any of his appearances.
In the original pilot for Day of the Dumpster, Squatt's name, according to the script, was going to be Grock. Additionally, while his actor was still Michael Sorich, he used a much deeper and more monstrous voice in contrast to the more comedic voice in the final series.
