Summer of the Baby Races / Summer of La Extraterrestre Tater is displeased that her parents used one of her Romancimorphs shirts as an improvised diaper for Baby Bud. Upon breaking up the incident, Buela reveals that Hacienda Hills' sister town, Fresadena, holds annual baby races, with the winner getting a lifetime supply of diapers. All of her children have failed. When Tater suggests that Baby Bud enter, Bibi is against it. They take a trip to Fresadena, where an ignorant woman misidentifies Bibi as Baby Bud's "nanny", inspiring her to join the race. The entire Ramirez-Humphrey family supports Baby Bud, and he does well in the race, with several babies being disqualified or out of the race. Baby Bud ends up falling asleep just before reaching the finish line, and Tater gives a speech about being proud of oneself. Her speech soon becomes moot as a minor earthquake carries Baby Bud across the finish line, with the Ramirez-Humphrey family celebrating their victory. While the primos go to the dentist, Tater is stuck at home with ChaCha while Pop does some backyard work. She watches an alien documentary and becomes convinced that ChaCha is, in fact, an alien, which she takes joy in. Soon, Tater believes that the government is after ChaCha, and they defend themselves against what they believe to be a government agent and other aliens who have been brainwashed. In the end, Tater realizes that the "alien signs" were simply ChaCha trying to take after her. The government agent was Buela returning from beekeeping classes to get honey for Pop, and the aliens were the rest of the primos with swollen mouths, as they all had cavities. ChaCha finally says, "I love you Tater".
