“They’re just going nuts.”

Toddler Mayhem

Reitman had a very specific vision for how the Mini-Pufts should behave.

According to Joseph, “The marching orders we got from Jason were that these are mischievous toddlers.

“The proportions are pretty similar,” he says.

Being Marshmallow Men, I think we had to do that.

It never went away.”
