(Another Buddhist thrift store find. This time it's a Thai frog rattle – essentially, a moktak-style percussion instrument with added sawtooth ridge. This last produces the familiar creak of a frog's call when the chukpi [the striking stick, meant to be clenched in the subject's jaws, but absent here] is run along it. Frogs are a common theme in Asia, where they're a talisman of good luck.
Though not a uniquely devotional object – despite clear parentage with doan paraphernalia, children often play with these, too – I'm always bemused to find this sort of thing amongst the rummage in such places.)
