But they were two bright that she falls down. Griffin agrees about how too bright they were, as well. Then, they test out Sanyoid's new 4D TVs that were so real, you'll jump out of your seat. And when Gustavo turned the TV, bats appeared in it, which scares Gustavo. Griffin then tells his technicians they should bring the realness down 30%. Later, Katie, Gustavo and Kelly tell Griffin that they are done testing his products and how they were bad, and that he can't keep them at Rocque Records against their will. But Griffin says the RCM Remote Family Security Home Control system can, and that it keeps unwanted intruders out and unruly teenagers in. Griffin then tells them that they're not going anywhere until they finish testing his products. The three tried to escape but because the Home Control system closed and locked at the doors in the studio, they couldn't. So they are trapped inside, and surrounded by Griffin's crazy tests, and that they could be anywhere. But according to Griffin, they were two tests left, starting with RCM's Innovative Wall Conferencing System, which he appears from and that it works great. And it finally comes to the final test, the Weight-I-Ator. Gustavo tells Griffin that they are not testing that thing till he tells them what it does. Griffin says that it is a internal cell accelerator that vibrates access weight at such hyper speeds that it reduces your body size up to 20% instantly.

Kelly says to Griffin, "And nobody leaves until we test it?" Griffin says that she is correct. So they test it... on Griffin.
