From Elevator Family On Ice:
“We need more refreshments for our party,” said Winona. “We don’t have enough fish and batter for everyone.”
As she spoke, a food truck appeared on the ice. It drove up to the Wilson’s shack and parked beside the ice carousel. On the side of the truck were the words:

MOM’S JUST FISH WAGON
GOOD LUNCHES AND DINNERS
MADE WITH THE WILSON FAMILY’S FAMOUS SECRET FISH BATTER

The side of the truck folded open. In the van stood a big-bellied man with a long gray ponytail.
“Mom!” the Wilsons shouted.
Yes, inside the food truck was none other than Milton Oliver Montgomery, aka Mom, the very man Walter had created the Wilson Family’s Famous Secret Fish Batter for.
