Item: handful of 2d4 frogs; one of the few weapons to which size class fine creatures are susceptible, particularly when in swarms. Attack stats adapted from the Giant Frog eating people:
Swallow: The frog makes one bite Attack against a Fine target it is Grappling. If the Attack hits, the target is swallowed, and the grapple ends. The swallowed target is Blinded and Restrained,
it has total cover against attacks and other effects outside the frog,
and it takes 5 (2d4) acid damage at the start of each of the frog’s
turns. The frog can have only one target swallowed at a time. If the
frog dies, a swallowed creature is no longer Restrained by it and can escape from the corpse using 5 ft. of Movement, exiting prone.
Encounter: weird-looking rabbit that has learned to defend its warren by casting Call Lightning by playing the rhythm from AC/DC’s “Thunderstruck” on a xylophone
