Passengers

The Passengers are characters in the Dumb Ways to Die parody, Queremos Vivir En Caracas. In said parody, they watch Stupe get decapitated in horror as he gets off the bus.

Bean 1
The first bean at the left appears as a yellow, oval-shaped bean, possibly Doofus.

Bean 2
The second bean to the right of the yellow one is a purple bean, who is square-shaped, with round corners, who bares a similarity to Doomed.

Bean 3
The third bean, in the second window of the bus, to the right of the purple one, is a light green bean, similar to Stupe. However, the bean could possibly be Botch.

Bean 4
The fourth bean, to the right of the green one, is a pink, capsule-shaped bean, assumed to be Dippy.

Bean 5
The fifth bean, to the right of Dippy, is an orange, peanut-shaped bean, known as Ninny. This suggests that Stupe's death takes place before Ninny's or all deaths take place in order that they are in the song.

Bean 6
the sixth bean, to the right of Ninny, is a blue, oval-shaped bean. This cannot be Numpty, because he was killed earlier in the song. It is most likely Numpty's Child (despite him not existing when the song was made).

Bean 7
this bean, at the right of the bus, and the Numpty-like bean 6, is a yellow, oval-shaped bean, presumably a copy-paste of Bean 1. This, or Bean 1 is Doofus. It's possible that there could be two Doofus in the song or that this bean is Señor Redcape without his cape (despite him not existing when the song was made)
