Lost in Space...Camp is an episode of the ALVINNN!!! and The Chipmunks series.
Theodore must prove he's got "the right stuff" when the Chipmunks and Chipettes head off to space camp.
Theodore's in the middle of a nightmare about crashing into the sun when Alvin wakes him up to hear Simon's news. Simon excitedly informs them they've been selected for the Interstellar Flight Academy. Eleanor and Jeanette are happy to go too though Alvin and Brittany aren't interested and Theodore is scared because of his nightmares. Simon, Theodore, Jeanette, and Eleanor arrive at the IFA and Simon is immediately separated from the others. The three remaining chipmunks are locked in a room with three other individuals and tasked with making it to the exit as they are floating. Unfortunately Theo gets sick. Missing Simon, he learns Simon was placed in an advanced group. A staff member lectures them for a few hours about the operation of a space craft before they are paired to test that knowledge in a simulator. Theodore is paired with a guy named Red, who's controlling and blames the munk for their failure. Ready to give up without Simon, Theodore is given additional practice with the help of Jeanette and Eleanor. Theodore calls Alvin to be picked up by Dave given the difficulty though Alvin refuses once he learns a bully is also involved. Instead Alvin motivates Theodore to prove the bully wrong. He contacts Eleanor and she and Jeanette give Theodore more practice at night before the final simulation. The simulation appears too real, causing them to panic and wake Simon up for his help. In the end Theodore is brought back and he receives a certificate of completion.
