I can see Squeek being a sort of like an insect like creature that hovers. I mean Munch is good in the water and Abe is good on land well Squeek could be sky.
Another theroy I wrote about Squeek was that he is a mutated Slurg curtesy of the Vykkers and sold to the Chroniclers as a new secret securty gone wrong. To guard the chroniclers bank valts in case Abe or Munch come and try to foil their plans. Since Squeek was once a normal slurg he would relise this and he would try to stop the Vykkers doing it on other Slurgs. What is sad though is the fact that he and others wouldent be abel to go back in being a slurg again. And live with the fact that he and others were never ment to be. I wrote all about this in my topic on "Another Squeek idea."
