"Maybe Alvin went in here." Simon says as the group goes toward a building.

"Hold it." A security guard says as he stops the group.

"Chipmunks and one guest." Simon says.

"Chipmunks, chipmunks." The guard says as he looks at some papers.

"I'm sure we're on the list." Simon says.

"Yep. Go on in." The guard says as the group goes inside and sees Alvin.

"Well we know he's here alright." Alexis says seeing Alvin wrecking havoc.

"We've got to stop Alvin quickly or our careers-" Simon then gets cut off by Theodore.

"Are history." Theodore says.

"Okay but how are we gonna stop him?" Alexis asks.

"Oh-ha! I found it. The antidote." Simon says as he looks in the book.

"Great." Theodore says happily

"Oh no. I have no idea where to find these ingredients. In earth marine ova, the lower limps of an amphibian, bovine oral organs." Simon says.

"Hey! The buffet table!" Theodore says as he goes over to a buffet table.

"Theodore this is hardly the time for a snack." Simon says as he and Alexis go over to Theodore before seeing what Theodore has on a plate.

"No Simon. Look. Theodore's found the ingredients you listed. What else do we need? We'll get them." Alexis says.

*Timeskip*

"Now only one more item. Gastro patta escar gota." Simon says as he is mixing the ingredients in a bowl.

"Got it." Theodore says as he goes back over to the table.

"What's with Alvin? He's acting like a-" Dave then gets cut off by Alexis as he comes over.

"Monster? We know." Alexis says as Theodore comes over and drops the last ingredient into the mixture before the group takes the bowl and walks away from Dave.

"Now all we have to do is catch Alvin and make him ingest this miserable goo." Simon says.

"Yuck! Even I wouldn't eat that mess!" Theodore says as he smells the mixture.

"Ditto. Better him than us." Alexis says.

"We have a problem. Apparently this stuff won't work unless Alvin eats it while he's upside down." Simon says.

"Great. How are we going to do that?" Alexis asks.

"Well first do you see him anywhere?" Simon asks.

"Unfortunately yes." Theodore says as the group sees Alvin being chased by a movie star.

"Guys now's our chance." Alexis says seeing Alvin and the movie star hanging upside down from a billboard.

"Here we go guys and we only get one shot." Simon says before the group places the bowl onto a scarf and uses it to launch the bowl into the air.

"We got him." Alexis says seeing Alvin get hit with the bowl and is beginning to eat the mixture and begins to fall with the movie star.

"Guys grab the other end." Dave says as the group uses a table cloth to catch Alvin and the movie star successfully.

"Yes! That was phenomenal!" A man says as he comes over.
