PITTSBURGH -- JuJu Smith-Schuster's 31-yard touchdown on Sunday brought out the 9-year-old in the Steelers.

Smith-Schuster got wide open for the second-quarter score against the Cincinnati Bengals, then executed an elaborate game of hide-and-seek with Le'Veon Bell, who hid behind the goal post while Smith-Schuster covered his eyes and pretended to count. Afterward, Smith-Schuster searched for Bell for a few seconds, then started to chase Bell out of the goal post once he spotted him.

Antonio Brown sort of stood there watching the whole thing, not sure what to do.

"The crazy part is JuJu and I thought about it," Bell said. "I came to JuJu with it, literally about 10 minutes before the game. I said, 'Hey, JuJu, if one of us scores, let's play hide-and-seek.' He's on it. We didn't even practice it or anything. It just kind of happened. That was us just being dramatic, creative on what we were going to do. I know JuJu and he loves doing celebrations. I know he was going to be the guy to do it."

The celebration was slow to develop but well worth the wait, probably up there with the Minnesota Vikings' duck-duck-goose routine. The NFL is winning with the decision to let players choreograph celebrations. And Smith-Schuster, 20, is showing his youthful exuberance with each score. In Week 4, he popularized the Dragon Ball Z fireball.

After the game, Smith-Schuster tweeted:

I want to thank the @NFL for letting us have lit celebrations! 😂🤗
