Chicken Little: This story is not a sequal so much as a spin-off featuring a character and scenario from an earlier Loxie & Zoot storyline. It's A Nood, Nood, Nood, Nood World (or, 'Nx4 World') was a crime caper that introduced, amongst many other new characters, police officer Tina Ellis.
Tina had visited the Koala Bay Bares with her family when she was much younger and she finds herself back there, along with her police colleague Sarge, in a more "official" capacity. Her very first appearance in 'Nx4 World' was on pages 9-10 although she doesn't really get into the story until page 46.
'Nx4 World' also makes constant reference to a mini-golf tournament to be held at the Koala Bay Bares... which is useful for understanding this particular story.
'Chicken Little' is not a sequal as most of it takes place in the week of time that is meant to elapse between pages 85 and 86 of 'Nx4 World'. It is like a story within a story. None of that is important to enjoying 'Chicken Little' but it might help give you a background context thru which to fully understand the references made within this story!
