Among the changed trap components in this version is the inclusion of a model toilet instead of a model bathtub. A version of the game featuring characters from the "Elefun and Friends" universe was introduced in 2014. Among the changes in this version, the trap is built before the start of the game, a spin wheel is used instead of dice, and the cheese pieces and their relevant rules are not included. Also in the 2010s, Hasbro introduced "Classic Mousetrap" with several major changes from the previous versions. The object in this game is to collect six cheese pieces. Instead of being eliminated from the game when caught by the trap, a player only forfeits a cheese piece to the opponent. The trap machine was also modified; most notably the crank gears were eliminated, and instead the trap is launched by directly pulling the lever with the plastic stop sign. "Mouse Trap" was adapted into a game show which was featured on the British children's television show "Motormouth". Child contestants take the place of the mice in a life-size board game. Game designer Marvin Glass (and his company, Marvin Glass and Associates), acknowledged that "Mouse Trap" had obviously been greatly influenced by Rube Goldberg's illustrations, though they refused to pay licensing or royalty fees. Glass also developed two lesser-known games based on Goldberg designs, Crazy Clock Game ("Crazy Clock") (1964) and Fish Bait Game ("Fish Bait") (1965), neither of which credit Goldberg's influence. Elderly and near retirement, Goldberg declined to take legal action against Glass—primarily because inspiration and ideas are not intellectual property that can be protected with a copyright, trademark, or patent—and instead chose to sell licensing rights for his drawings to another toy company, Model Products, to help secure the rights to specific intellectual property that he could own and receive royalties from. In "Crazy Clock Game", players race to build a Rube Goldberg machine. The game comes with a pack of cards, each illustrating how one piece of the machine fits in. The deck is dealt out to the players. The player starts with the first card, card 1; players then play as many cards (install as many machine components) as they can, then pass to the next player. After fully assembling, they take turns trying to operate the machine, starting with the player who installed the last component; the winner is the one who first succeeds. "Fish Bait Game" is simpler than "Mouse Trap". Players play as fishermen and build a contraption to catch a man eating fish.
