The argos aliens have an arrival song (2013 version)

lyrics

Chuck: argos alien dad is pregnant back in 2013

Trishna, willow and olivia: he's pregnant, yeah he's pregnant

Chuck: he says hello gherkins while alien mum shops online

Trishna, willow and olivia: he's pregnant, yeah he's pregnant

Chuck: alien dad cries, and cries, and cries

Trishna, willow and olivia: he's pregnant, yeah he's pregnant

Chuck: at the bus where he sits next to a person and said "it's kicking"

Trishna, willow and olivia: it's kicking, oooh it's kicking

Chuck: alien mum says breath slower to him

And the aliens are ready for a new arrival

And at the end, they met a new baby alien named blue

Trishna, willow and olivia: get ready for a new arrival

Trishna, willow, Olivia and mandi: welcome to the land, baby blue
