-As @askpendulumdepot and @gart-the-golden-child took note of Barb's brief recall of her adventure into the depths of Lake Bottom Barrel, she felt compelled to provide more context.-
Barb: When I was out on one of my night walks, I found the place abandoned and thought it would make a good picnic spot. I didn't know about any of the rumors, but Robot told me about the Oil Barrel factory accident that ended up burning down, sinking and spilling oil into the lake. That's why it's called Lake Bottom Barrel. What most people don't know however, is that there are mechanical survivors who've created their own small community down at the bottom!
They didn't get petrified with rust and corrosion because of the oil that's saturated into the water, so their metals are always protected!
According to Robot's friend Maurice, it also turned out that it was this giant Mechanical Serpent they call "Utekna", that attacked and sunk down the Oil Barrel factory. She was really mean and very territorial, but Monster was able to pull out the crystal on Utekna's forehead, which must have been like a splinter she got from her crystal den in the caves, and it made her grouchy. Now she's super docile! Still territorial, but now she protects the residents of Bottom Barrel, so long as they provide her with plenty of gems and treasure.
It might actually be for the best that you don't visit there, Gart. Utekna would easily mistake you for being an appetizing piece of gold! That's why Robot almost got eaten by Utekna because Robot is so brightly colored and shiny, and likely got mistaken to be a gem for her to snack on.
It was scary, but Robot found closure with Maurice ending up being alive this whole time! We still go down there to visit Maurice every now and then, so long as we cover Robot up in dirt to dull his shine.
-Barbara looked down between Gart and Pendulum bringing up the silly formula. She couldn't deny that Pen would try stealing the blinking lights formula if he could, but still had no suspicion that Pen would use her to do it.-
-Robot, on the other hand, had his suspicions that Pendulum was up to no good, especially when it came to Barb. In fact he had half a mind to confront Pen over how he carelessly brought Barb out in such a public space where she could risk getting exposed. At least at Pen's solid lights factory, Barb could remain more hidden.-
-Robot takes out his binoculars from his hatch and zooms in-
Robot: I got my eye on you, Pendulum... I know I'll catch you tangled up in your little twisted web of LIES-
-Barb noticed Robot watching, and she gave him a wave that made it obvious to everyone else that Robot was in fact, watching-
Robot: Oh crud- -the binoculars slips from his claws and he tosses them away immediately-
Barb: Anyways, what do you carry around in that handbag, Gart? I like to carry a brick in mine. Maybe two. I can't legally have a wallet, or ID, so I just carry the bricks to feel like I have something. And I had to steal the bricks! ..... I don't have a lot of stuff-
