No punchline, just amusing-looking. It’s part of a teaser graphic I’ve been doing for an organisation’s events.
The wocka’s an old character I’ve been using on and off for more than a decade… some old stuff here (2005), here (2002, I think), and here (1999?).
You forget the classic Wocka from the Water Conservation project of ’96!
I hope all copies have been erased… if it ever surfaced I/we would never hear the end of it!
