Started doing some to-scale size references for Redwall-verse species, including some speculative ones (and corrected identifications, such as Jacques's few infamous instances of "crested lizards"... those are newts, buddy).
All the creatures in this series are obviously much less tiny or gigantic in proportion to each other than their real-life inspirations. Kinda got to do that to make a building useful for both small mice and massive badgers and otters!
The vast majority of reptile and amphibian species are regarded in-universe as part of the "vermin" class, some regarded even more negatively than others (snakes). The single exception to this rule is frogs, which seem to vary between having an ambiguous class to being tentatively considered "goodbeast", usually only by acknowledgement that they also are targeted by hunting carnivores more staunchly considered in the vermin category. The frogs in the series do not seem to embrace their advantageous class placement, and treat "vermin" and "goodbeast" alike in accordance to situation--a hare endangering your tadpole nursery is just as urgent as a ferret trying to spear you.
Of course, there are exceptions, such as poor Croikle, who isn't even really treated as a sapient being by the "goodbeast" creatures around him, despite knowledge that frogs in general are sentient and sapient.
