Yaffa's Creatures on the Loose! #1 x 3

Page Publications' Creatures on the Loose! #1 was published c.March 1978:

This issue was recycled as Creatures on the Loose! #3 c.February 1980:

The only differences between the two issues are the issue number and price, which appear to have been superimposed on the #3 over the initial number and price of #1, and the indicia differs between the two. There is also a marked difference in the printing which affects the colours.

This issue was recycled as an unnumbered digest-sized edition retitled Creature Feature:

The recolouring uncovers some of the linework which was barely visible in the murk of the first two editions, but they still didn't manage to colour the clouds correctly. Compare to the cover of Marvel's Creatures on the Loose #12:

The contents of the Yaffa editions appear to be the main features in Marvel's Creatures on the Loose #'s 10, 11 and 12, some of which are reprints from previous Marvel issues and modified to some extent in this series.
