"That's why I'm here, of course. Panju. He's in trouble again. I wanted to just send a Howler but Padma insisted I come in person."
-- Ron Weasley (CC2.9)
always getting into trouble
Panju does not seem to be an Indian name. However, there is an island near Mumbai called Panju Island (Wikipedia), as well as a Tamil language film called Panjumittai (meaning "cotton candy") (Wikipedia).
When time is put right again, Panju no longer exists.
