All I can say is this: Make sure your friends/family have a sense of humor. Last year, my son and his girlfriend made this for Halloween. Adam was hanging around the table, talking to a friend. He reached over, grabbed a piece of Tootsie Roll and popped it into his mouth. "Mmmm....I love the turds best of all," he said nonchantly. His friend excused himself and left.
Prepare cake mixes and bake according to directions (any size pans).
Prepare pudding mix and chill until ready to assemble.
Crumble white sandwich cookies in small batches in food processor, scraping often. Set aside all but about 1/4 cup.
To the 1/4 cup cookie crumbs, add a few drops green food coloring and mix using a fork or shake in a jar.
When cakes are cooled to room temperature, crumble into a large bowl. Toss with half the remaining white cookie crumbs and the chilled pudding. (Mix in just enough of the pudding to moisten it. You don't want it soggy. Combine gently).
Line new, clean kitty litter box.
Put mixture into litter box.
Put three unwrapped Tootsie rolls in a microwave safe dish and heat until soft and pliable.
Shape ends so they are no longer blunt, curving slightly. Repeat with 3 more Tootsie rolls and bury in mixture.
Sprinkle the other half of cookie crumbs over top.
Scatter the green cookie crumbs lightly over the top. (This is supposed to look like the chlorophyll in kitty litter.)
Heat 3 Tootsie Rolls in the microwave until almost melted.
Scrape them on top of the cake; sprinkle with cookie crumbs.
Spread remaining Tootsie Rolls over the top; take one and heat until pliable, hang it over the side of the kitty litter box, sprinkling it lightly with cookie crumbs.
Place the box on a newspaper and sprinkle a few of the cookie crumbs around.
Serve with a new pooper scooper.
