This time Mounie was the scorer, rising above Bournemouth's defenders to head in Mooy's inswinging free-kick after Lewis Cook had brought down Jonathan Hogg.
Mooy was carried off with a knee injury in Huddersfield's 4-1 victory over Bournemouth.
"We had hard fixtures behind us and now start games when we can be competitive", said Wagner, whose team are now just four points behind the 10th-placed Cherries. He got a cut over his knee - he got some stitches as well.
"We should look as hungry, if not hungrier than them - that's no excuse for us".
"At the minute I cannot answer this question seriously".
Steve Mounié demonstrated the sort of early-season form that allowed him and Huddersfield Town to surprise the Premier League, scoring in a victory that offered a major boost to his club's hopes of avoiding relegation.
Paul George scores 29 points with 9 rebounds for short-handed Thunder
After a slow start, Walton got his answer. "I don't know if whether I'm going to LA, or what I'm going to do this offseason". George started strong with 12 points in the opening 6:52, hitting his first five shots including three 3-pointers.
Midfielder Pritchard, a £14m January signing from Norwich, collected Mounie's cut-back to sweep in his first goal for Huddersfield after just seven minutes.
"We needed a few minutes at the start where Bournemouth were strong but after that we played superb football".
The Belgian striker has worked his socks off in a dogged campaign where Town have scored just 19 goals in 26 Premier League games.
"It was our idea to press the opponent high up the pitch and win the ball".
