Tommy & Kat head out to the desert, searching for creatures to place in their school-project terrarium. They end up running into Prince Sprocket, who shrinks them down to mere inches-high size! The two Rangers are left to fend off a normal-sized (but giant to them) tarantula, who serves as the inspiration for the evil Tarantabot monster their teammates end up facing. Meanwhile, Bulk & Skull aren't far away, hired to investigate claims of gold in an old mine. One of them finds gold of a Ranger-kind instead!
