The Great Chipmunk Detective is an episode of the ALVINNN!!! and The Chipmunks series.
When Miss Miller gets robbed, Eleanor and Theodore promise to find the culprit and bring them to justice. 
While on their deck stargazing, The Chipettes spot a police car stop in front of the Miller House so Eleanor sets out to learn what's happening. She overhears Miss Miller explaining to Officer Dangus the most recent robbery she's had, but once he learns the stole item is carpet cleaner, he leaves with the intent to just file a report. Eleanor compiles a list of everything stolen, which includes 100 bottles of carpet cleaner and ten dozen leprechaun glasses. As payment for her time, Miss Miller insists she take a pair of leprechaun glasses, which she later gives to Theodore for payment for his assistance. Theodore looks online for sales of the carpet cleaner while Eleanor surveys Miss Croner, Alvin, and Simon across the street. Her partner finds a seller and the pair go to the address only to find Officer Dangus. Eleanor discovers a warning note on Theodore's back so she commits to following the officer. After a high speed trip around town, Dangus discovers the two in his car. Eleanor accuses him of the theft and he explains his mom and uncle keep buying stuff they don't need. On the way home, they learn Miss Miller was robbed again and are told to drop the case. Theodore finds another note at school the following day, and hearing the buzz of one of Miss Miller's workout belts, they two set out to find the student responsible. They discover it's Cheesy, but he refuses to talk. They keep watch at Miss Miller's house when they overhear Cheesy and Miss Croner talking, leading to the discover of the stolen goods in her basement. Miss Croner explains she only meant to stop Miss Miller from wasting her retirement money. The two talk with Miss Miller before Dangus arrives claiming he solved the case.
