The magic contained inside The Madrigal household is difficult to quantify. From the outside, the family's house, known endearingly as Casita, seems modest enough. Once inside, however, the square footage appears to shoot off into a mystical realm where the rules of physics no longer exist. This is put on full display during Antonio's gifting ceremony, where his magical abilities are revealed and his new living quarters are unveiled. The glowing, golden bedroom door opens up into expansive jungle complete with its own existing ecosystem, which is immediately filled with animals from the surrounding area.

While everyone is gasping at the grandeur that is Antonio's bedroom, other children's jaws drop and one of them shouts, "It's bigger on the inside!?" The line is unassuming in and of itself, as the room is definitely worthy of exclamation. Those who have spent nearly 300 hours of their life following the adventures of "Doctor Who" may be uncontrollably smirking though. The line could be seen as an intentional nod to the Doctor's description of the TARDIS and its dimensional transcendence. The inside exists in a different dimension than its exterior, but more simply put by the Doctor themself, "It's bigger on the inside than it is on the outside."
