In the scene with the fish tank, the mother of the household refers to one of the fish as a "Poecilia latipinna" from the Amazon. Mimi-Siku agrees with her and even gives its native name. However, Poecilia latipinna, commonly known as the Sailfin Molly, actually comes from North Carolina down to Texas and the Yucatan Peninsula. Also, the fish in the tank are in fact Rift Valley cichlids from Africa.
In the car, when Mimi-Siku shoots the fly on the sun visor, Michael puts it up once, then tells Mimi to put his blowgun away. Then right before Michael exits the vehicle, the sun visor is down again, and he puts it back up as he leaves.
