The boys forget to get Chata a gift for Abuela Day and in a panicked move, they pretend that the bongo drums they borrowed from Xochi are for her. Knowing they have to return the drums, Victor and Valentino pretend to be burglars to steal the bongos back.

Vic makes a ghost friend but when she interferes with his shot at being part of the cool kids’ Tlatchtli team, he must choose between the two.

When Vic and Val accidentally bring a fungus into Xochi's garden, they have to find a way to stop the monstrous plants it creates.
