But their surprise present for Lucy turns into a trap when President Penguin from Pluto plots to take over Earth. President Penguin is peeved because Pluto is no longer considered a real planet. Now he plans to make things very unpleasant for anyone who stands in his way. Can Ricky, Lucy, and their friends defeat this tiny terror and keep Squeakyville safe?
