Eh, we don't know how she/it won that battle, & they seemingly had a piercing weapon.
It's curious that the giant sun robot seemingly bled & had organs.
At the start of the episode, with Olivia, it seemed like whatever Guinevere was being pulled by had "blue blood", & it seems like employees of... whatever the amusement park's name is, seem to have that stuff... affecting them?
Maybe people in general with their trash dumping?
Personally, I wonder how often we'll see Guinevere's idyllic perspective. They've dived into the darkness with little signs of exiting it so far.
....Come to think of it, the big sun robot threw a dome through the air, right?
Surface area mitigates how much of that Frankie/Frank/Franscesca/Franklin (Only by Sparky, AFAIK.)/Frank (Only by a worker of Sparky's, AFAIK?) & Andi/Andrea (So far, only Guinevere & the creatures/space animals have called them their full names, albeit, seemingly after "rebooting" based on the ending.) experienced, though.
The "creatures" (called so by the official captions.), & "Space Cat", "Space Tapir" & "Space Penguin" by the credits are curious. When Sparky's in a room of the ship(?), we see them approach off of a countertop & descend to the floor, in their glowing, vibrant forms, then Franky hears words from them that... help her decide what to do.
We then see their somewhat... shoddy, less vibrant-looking toy/construct form get picked up.
So:
A. Frankie is really messy & the toys/robots were on the floor to begin with, & them being on the countertop &/or descending from that was the delusion. (We see them get picked up, so it can't be them being on the floor that was the delusion, right?)
B. They're on a boat, & despite no tilting/turning being shown & the surfaces being level when they move, we assume they fell off because the boat tilted or something, despite the lack of turbulence.
C. They were real somehow. (Odd. Doesn't seem like a magical setting, & their less vibrant forms seen suggest they aren't animate/functional machines, maybe? Frankie is good with tech, right?)
