Would the Irish púca/pooka/phouka be an influence on this bellicose leporine marginalia?
Intruiging report: from 1290 to 1320, many medieval manuscripts have marginal art of knights (and others) battling giant snails. https://upvoted.com/...edieval-europe/

In Terry Gilliam's commentary for his lost animation for Monty Python and the Holy Grail, he imagines how bored and resentful younger sons who had been sent off to monasteries while their elder brothers got to be knights may have gotten a sort of revenge by depicting them in battles against ridiculous opponents, especially snails. Thematically, it's one type of hard-shelled opponent vs. another.
(Monty Python and the Holy Grail, for such a silly film, was extensively historically researched.)
