Blue River Creek has a problem: there's a pet thief on the loose! Or at least Sofia and Iggy are convinced there is, when their pets go missing. But as a scientist, Ada knows it's important not to jump to conclusions and instead take the real facts into account. How will they find out what really happened to the town's pets? Using the scientific method of course! By forming a hypothesis, collecting data and doing experimentation, the questioners must find the missing animals before even more pets disappear!
