lol, yes, they do seem to be a continuing trend. Someone once said the ribcages seen at the very start of AE look too big to be a Mudokon's, but I haven't bothered to check it myself.
I'd quite like it to continue a mystery, actually. It could take the place of the mystery of how Abe's Moon formed, which was answered following Lorne saying it would never be answered.
We have to have something to speculate about, after all - even if we have already done so a dozen times.
