There is a known bug in the current version of Ooblets (v1.4.43) in which the seasonal event Oobmobile kiosk will only appear during the Wintertime Event and not during the Halloween Event. This makes it appear impossible for players to get the Halloween Oobmobiles. This guide will offer a couple methods you can use to get them in spite of the bug!
Whenever an Ooblet receives their Oobmobile license, they are gifted a random Oobmobile for free. It has been confirmed that if you get a license during the Halloween event, the Halloween Oobmobiles are among the possible Oobmobiles you can receive. This gives you a 4/34 chance to receive one of the Halloween Oobmobiles whenever you get a license during the event. If you save the game just before getting the license, you can soft reset until you get the one you want. While this method leaves a lot up to RNG and can potentially be very time consuming, it does not require you to manipulate the game.

Ooblets uses the system clock of your device to determine which seasonal event is active, if any. By adjusting your system clock, you can manipulate the game into changing the active seasonal event to whichever one you want right now instead of having to wait for the usual time of year (this is sometimes referred to as “time travel”). If you are willing to adjust your system clock, this method is much faster at guaranteeing that you will get Halloween Oobmobiles.
If you play on PC, check out my guide for how to Time Travel on PC with RunAsDate. If you play on a different platform, you may want to first familiarize yourself with how to adjust the system clock for your device.
The way this method works is pretty simple. Since we don’t have access to the Halloween Event’s Oobmobile kiosk during the Halloween Event itself, we instead trick the game into having the Wintertime Event’s Oobmobile kiosk sell us Halloween Oobmobiles instead. In short, the seasonal event Oobmobile kiosk only sells one Oobmobile each day, and the one it sells is randomly selected the moment your character wakes up at the start of the day. That selection is saved, and it won’t change until you go to sleep again and start a new day. So, here’s what you do:
