Proposed Canon

A type of Dwagon.

They, along with yellow and purple, are described as one of the weaker varieties of dwagon.^{Erf-b1-p062Erf-b1-p064}

Speculation

Its breath weapon resembles a bubble of pink bubble gum and, presumably, causes the target to suffocate.^{Erf-b1-p031Erf-b1-p050Erf-b1-p057}There is some evidence that suffocation isn't the only effect the breath weapon has^Erf-b1-p057(note the Woodsy Elf that has apparently croaked from a hit to the stomach [actually, you may notice that the elf in question has been stabbed through the stomach in a previous pannel by the dwagon's tail]).

Pink dwagons may have lower move than some other varieties of dwagon as they were not used for the initial attack on the seige (in which all dwagons had 56+ move)^Erf-b1-p046a, but were described as being strong examples^Erf-b1-p058 (presumably high level) of their sub-type. This is not conclusive as the placement of high-level, weak-seeming dwagons at the back of the ring formation may have been a ruse by Parson.
