I mean my name is a pun on ni and doodles. But as for ocs off the top of my head I've got:
Hymn which is less of a pun name and more of a joke, since when I was naming him I said 'what should I name it' by accident, as was corrected by my best friend with a 'him' so of course my joking reply was 'ok sure, Hymn it is'. And hymn it was.
Willey since she's a trickster~ But also it shortens to 'Wy' which is what people say after she scams them, to which she replies with a 'wy not~'
