When cakes are cooled to room temp., crumble into a large bowl. Toss with half the remaining cookie crumbs and chilled pudding. Line litter box. Put mixture into box. Put 3 unwrapped Tootsie Rolls in microwave safe dish and heat until softened.
Shape ends so they are no longer blunt, curving slightly.
Repeat with 3 more Tootsie Rolls and bury in cake mixture. Sprinkle the other half of the cookie crumbs over top. Heat 3 Tootsie Rolls in microwave until almost melted. Scrape them on top of the cake and sprinkle with cookie crumbs.
