"Did You Myth Me?"
"A Bad Altitude" is the 50th episode of Inspector Gadget.
While planning vacation with Penny and Brain, Gadget gets another mission from Chief Quimby: He has to go to Everest Island to stop Claw from destroying the hotels there if he couldn't be able to receive their money.
Gadget arrives on the island, along with Penny and Brain. However, Claw has other plans: He plans to sink the island with the resorts, except of its peak with his own hotels. After an unsuccessful attempt by the M.A.D. taxi driver to do the Gadget clan in, the trio stays at Claw's hotel that is run by Ricardo, a M.A.D. agent who poses as the manager. Gadget lies on a bed with the spines that can destroy him, but Brain saves his master.
The next day, Gadget goes for town to warn the other hotels from Claw's attempts to destroy them. After another failed attempt to finish Gadget by Ricardo, the taxi driver takes Gadget to the town. The driver activates a sleeping gas, so Gadget falls asleep. However, Gadget makes the driver fall asleep, too. The taxi now goes right to the M.A.D. truck that contains the explosives to sink the island. Brain wakes the driver up and they dodge the crash with the truck, but land in a hotel swimming pool. Gadget tries to warn the hotel managers about plans to destroy their hotels, but the managers think that Gadget wants to destroy the hotels and call the police. The police chases Gadget, who chases Brain, thinking that he's a M.A.D. agent.
Meanwhile, Penny finds the salt water footprints on the hotel's floor and discovers that they belong to a M.A.D. agent in a diving suit and they're leading to an elevator. Penny finds out that the elevator goes through the island to the ocean. She finds the underwater hideout and discovers Claw's plan, but she gets captured and locked in a room full of diving suits and almost empty scuba tanks. Penny takes one of the suits and the almost empty scuba tank and swims back to the surface, but she gets captured again and is chained to a piece of metal. With her tank now empty, Penny unchains herself with taking off the tank before swimming back to Claw's hideout. Penny tries to use the elevator to escape, but the explosives are there. So she uses her computer book to make the elevator go back up, making Claw's hotel explode. Penny takes the full tank and swims back to the surface where Quimby arrives and arrests the M.A.D. agents while the police release Gadget, who releases Brain.
