Although Captain Cosmo was a small dog, he had a very important job on the space station. He was the leader of the station's famous detective team. One morning, he received a message about a new competition. All the teams on the station had to solve a mystery. The prize was a special golden bone. Cosmo wanted to win more than anything.
Because the competition was difficult, Cosmo knew he could not solve it alone. He called his three best friends: Mia the mouse, Leo the lizard, and Pip the parrot. "If we work together, we can win," he said. Each friend had a different skill. Mia was small and could go into tiny places. Leo was strong and could move heavy objects. Pip had sharp eyes and could see things far away.
