Spotty is having one of her routine inspection days when Rusty reports a strange encounter at the Oasis. It takes Spotty no time at all to deduce that an intruder has broken into the Little Robot world and they are about to be invaded. She quickly mobilises a Little Robot task force to deal with the crisis only to get captured herself. Soon, however, she discovers what we knew all along - the so-called invader is really Stretchy's latest invention, a remotely-controlled Collectabot.
