Doc Hogg pays a special visit to the Big Blue House to give everyone a checkup. Before he arrives, Pip and Pop dress up as doctors and pretend to give a checkup to Treelo. Bear tells the viewers all about Doc Hogg and what doctors do. Later, Doc Hogg gives everyone their checkup, but Ojo seems to have disappeared. Bear finds her hiding with Snow Bear --- it turns out that she's scared of getting a shot. Bear helps her out by teaching her a special song that Doc Hogg once taught him.
