In the next episode of "The Last Man on Earth," Carol Pilbasian (Kristen Schaal) and her husband Phil Tandy (Will Forte) baby-proof their house in a big way.

The trailer for the upcoming installment titled "La Abuela" was just released recently and showed Pilbasian and Tandy looking worried about their baby who will be coming into this world very soon. They inspect their new house which was previously owned by a notorious cartel leader and realize that they have their hands full. They see that there is a lot of work to be done to make the house, as well as the whole estate, baby-proof. Tandy decides to take it a step further to make it safe for his future kid.

He packs a ton of Styrofoam balls onto the staircase and demonstrates to Pilbasian how safe it is just in case anyone falls. All of a sudden, he jumps on the heap of Styrofoam and slowly sinks to the bottom. Pilbasian is at the side and watches the child-like Tandy pop his head up from the stairs. It remains to be seen if the couple will push through with their crazy plan and if Tandy has more quirky solutions to baby-proof the place.

In the last episode, Pilbasian and Tandy wanted their group including Melissa Chartres (January Jones), Todd (Mel Rodriguez), Erica (Cleopatra Coleman), and Gail (Mary Steenburgen) to stay close together. However, they wanted to live somewhere else further apart from them. When Todd suddenly fainted in the supermarket, everyone had to rush to get him and bring him to the clinic. Melissa and the rest of them eventually realized they all needed to stay together just in case of an emergency.

"The Last Man on Earth" season 4 episode 5 will air in two weeks on Sunday, Nov. 5 at 9:30 p.m. EDT on Fox.
