Striker says Blues will be aiming to put things right next week against Scunthorpe after Rochdale point.
Mooney struck from the spot with half time approaching, before Ryan Leonard found the net soon after to put Blues in command.
But Keith Hill's men battled back and ended up taking a point back to Lancashire.
“We’re disappointed,” a frustrated Mooney said after the game.
“Being 2-0 up at half-time you hope to be able to do enough to win the game but credit to Rochdale for coming back and we could have lost it at the end. We will probably take a point in the end.
“We didn’t start the second half as well as we would’ve liked but both their goals came from set plays which is frustrating. We will look at that and hopefully it doesn’t happen again.
“I was happy to score the penalty but I would rather have gone another five or six games without scoring in favour of us having got the three points.”
But Mooney insists Blues have to clear the result out of their system quickly and be ready for a better performance next week against Scunthorpe United in the Emirates FA Cup at Glanford Park.
“Rochdale are a good side. We need to take the point and move on. We need to dust ourselves down now and be ready for a big FA Cup game next weekend.”
