The Seasiders dominated their hosts for over an hour on a wet afternoon in West Yorkshire, only to then fall behind to Anthony Gerrard's first goal for the Terriers.
Substitute Nathan Delfouneso converted Tom Ince's cross in stoppage time to rescue a point, but Appleton was adamant his side should have been travelling back to Lancashire with all three after carving the opposition back four open on numerous occasions in a one-sided first half.
"When you've get a set of players like we have who are very creative, good footballers, good technique, eventually I do believe someone will take a tonking," said Appleton, who insists he is still unaware of any proposed January switch to Liverpool for star winger Ince.
"I'm not sure who, where or when, but someone's going to take an absolute tonking off us."
When asked whether it should have been three points instead of one Appleton added: "I think that's the biggest understatement anyone's ever said to me after a game.
"I said to the players, `don't enjoy the game until we're in front', because it was almost too easy at times we were playing so well.
"A lapse of concentration, a free header from a set play, and you're up against it for a while because they've got their backs up and something to hold on to."
