The Slovenian scored 41 points alongside 12 rebounds and 12 assists to help his side snap a four-game losing run in spectacular style, as they edged a 116-113 win over the Golden State Warriors.
It takes Doncic to three for the number of 40-point triple-doubles in the NBA this season, while no other player has yet managed one.
Kidd jested that it was not enough for a player of his calibre and stressed the 23-year-old remains a generational talent.
"It's getting boring," he quipped. "I mean, let's see something different. Maybe [he can] do it with his left hand. I'm just joking.
"Look, he's one of the best in the world, and that's what he does. Some of us can take him for granted. The man is special."
Doncic, who leads the NBA scoring charts this season, was exhausted but delighted to help the Mavericks turn matters around after a tough end to November.
"I just participated, giving everything I got," he added. "I was really tired at the end, but we needed this game. I think we deserved this win, and we for sure needed this win."
The Warriors came close to forcing overtime, with Klay Thompson missing a late three-point opportunity after the ball rimmed out, to Doncic's relief.
"I was scared, I'm not going to lie," he added. "It's Klay. He's not going to miss many open shots. I was really happy when it didn't go in."
