Beachcomber finds a stream of golden liquid that renders his hand invulnerable. Unfortunately, the Decepticons do too, and decide to take a dip.
- Japanese title: "Mystery of the Golden Lagoon"
Beachcomber, Powerglide, Seaspray, Perceptor and Warpath are taking a walk along the beach when they are attacked by Blitzwing, Ramjet and Thrust. In the middle of the battle, pacifist Beachcomber takes cover and finds a secluded glen full of flora and fauna right out of a Disney cartoon. In the middle of enjoying this impromptu petting zoo, the glint of gold catches his eye. In the middle of the glen is a pool of golden liquid he dips his hand into and identifies as “electrum.” A rockslide sends him back to where he came from, just as Thrust flies over the glen and makes the same discovery. Thrust jumps into the pool and comes out completely covered in the gold liquid.
Beachcomber arrives back at the battle as the tide is turning against the Decepticons. Just then, Thrust appears and survives a powerful Autobot barrage without sustaining a scratch, thanks to his electrum coating. Warpath shoots an opening into the cliff face that he, Powerglide and Beachcomber hide in, while Thrust kidnaps Perceptor and Seaspray.
At Decepticon headquarters, the Autobots are imprisoned while Thrust notifies Megatron of the electrum pool. They hurry off to the glen and Megatron orders Starscream to jump in. When he emerges, Megatron shoots him, but the blast bounces off. The rest of the Decepticons jump into the pool and emerge, then have fun shooting each other. Megatron declares the Autobots are finished as the glen around them burns and the animals cower.
Powerlide, Beachcomber, Warpath, Mirage and Smokescreen regroup and prepare to go after the Decepticons again. Beachcomber hasn’t told anyone about his discovery yet. The group rushes off and meets up with the electrum-plated Decepticons, and are quickly dispatched because their weapons have no effect. More Autobots join the battle, but their weapons are useless. Beachcomber realizes that they’ve found the electrum and drives off.
The Decepticons return to headquarters and Starscream forces Seaspray and Perceptor to fight each other. Soundwave rushes off to tell Megatron as Starscream gives the Autobots weapons.
Smokescreen, damaged from the battle, asks Omega Supreme to help and the giant Autobot declares (a bit prematurely) that failure is impossible.
Meanwhile, Beachcomber arrives back at the glen and finds the Decepticons have burnt it nearly to the ground. He is captured by Blitzwing while Soundwave tattles on Starscream. Megatron orders everyone to fight Omega Supreme. When they attack Omega fires, but even his weapons have no effect and he falls under enemy fire. Megatron sets his sights on Autobot headquarters next.
At Autobot HQ, Mirage reports on Omega’s defeat and Optimus Prime can hardly believe it. Teletraan 1 reports a single word to them – electrum. Prime recognizes its significance and sends out teams to try to find it.
Powerglide discreetly follows the Decepticons and sees them swimming in the electrum. He flies off to report the discovery to Optimus.
Megatron gives the task of dispatching Beachcomber, Perceptor and Seaspray to Starscream. When Skywarp and Thundercracker come to take the prisoners to Starscream, Beachcomber forgoes his pacifist ways and overcomes both of them. He frees Perceptor and Seaspray and they swim back to the surface and head toward the golden lagoon. With Dirge left alone as guard while all of the others head to the fight, the trio takes him out, just as Prime and the rest of the Autobots arrive. Beachcomber invites them to jump into the electrum with him.
Back at Autobot headquarters, Megatron and company attack but they discover the base is empty. Megatron orders everyone back to the lagoon, where the electrum-coated Autobots are waiting for them, including Omega Supreme. The two sides fight, but since their weapons are useless the blasts bounce off and destroy the countryside around them. As the battle continues, the electrum on the Decepticons wears off. His advantage lost and seriously out-gunned, Megatron destroys the lagoon and orders a retreat. The Autobots cheer their victory, but Beachcomber laments the destruction of the glen.

Animation and/or technical glitches
- In Blitzwing's first two appearances in this episode, his head is gold, but it becomes purple before he transforms into his jet mode.
- When Warpath voices his excitement about KAZOWYing Decepticons, Powerglide reminds him that it's a rescue mission and not "the Charge of the Light Brigade", a catastrophic cavalry charge during the Crimean War.
- When Starscream dives into the pool of electrum, he holds his nose.
- When the Decepticons enter the electrum pool, you can't tell whose Starscream, Thundercracker, or Skywarp.
- Also, it appears that the Seekers' guns can become handheld rifles.
