The Orbble Juice is the juice that Wander and Sylvia use to travel through the WOY Universe. It is kept in a small jar with a looped wand inside that looks remarkably like a soap bubble. When the wand is taken out of the jar and moved rapidly, forms a bubble. This can be done on a planet or in space. The orbble bubble expands to hold one or more people and is typically large enough so that passengers can stand upright but can be easily destroyed by any sharp objects. To move and steer an orbble, the passengers only need to walk or run inside it. The faster the passenger runs, the faster the orbble moves.
The orbble juice is obtained from the Orbble Pump, a machine designed so that when used, it refills Orbble Juice. However, the process takes an absurdly long time. It looks like a complex pump machine. But, when Wander & Sylvia arrive at an abandon orbble station there are two pumps looking more simple and less of a wait; one on the left is regular, the second is Time orbble to take the user through their own timeline.
An orbble provides a pocket of air that allows the passengers to breathe and is apparently self-replenishing. Orbbles are semi-permeable, allowing objects inside to pass through the surface, which is continually rotating. Objects or people can pass through the surface if someone from the inside reaches out to pull them in, but otherwise the surface is fairly durable. During their escape from a derelict ship, Sylvia created a second bubble by pushing Wander and Captain Tim away from her. When Captain Tim attempted to remove Wander's heart, Sylvia was able to merge the two bubbles back together and then threw Captain Tim outside. The spider was not able to break the bubble and get back in, but it was able to grab a part of it with its teeth. ("The Pet") However, orbbles can be punctured by very sharp objects such as asteroids or by strong impacts such as a gargoyle's wings. ("The Bad Guy") Sound is able to pass either direction through the surface, as evidenced by Sylvia and Wander being able to talk to each other while in separate orbbles.
Orbble Juice can eventually run out. After crash-landing on an asteroid fragment, Sylvia convinced Wander to pretend to be a bad guy while visiting Doomstone while they searched for more. Wander was so convincing that Papa Doom agreed to a trade, and after he and Sylvia helped the residents to show their true nature, Papa Doom gave wander a jug with enough juice "to get you guys wherever you want to go".
