Magic bus

The magic bus is a vehicle in Magical Vacation driven by Balsamico. It serves many purposes, such as party management, warping between realms, searching for hidden items, and freely restoring HP and MP. It also acts as a warp point on the world map, and can be warped to regardless of where it is. Searching the magic bus is the only way to obtain the washroom set.

Party management
Swaps classmates, hidden characters, and magic dolls in and out of the party. While a character is on the bus, they can still be used to bewitch a magic doll.

Rest
Fully restores all active party members' HP and MP for free.

Ride
The player takes control of the bus, and random encounters will not occur. This function cannot be used in the Abyssal Realm.

Search!!
The party scavenges for items around the bus. New items become available as the game progresses.

Warp
Warps the bus across realms. Its default spots are Ricebird Fields in the Light Realm, Eastern Forest 2 in the Dark Realm, and The Great Rock in the Abyssal Realm.

Search!! items
Although items obtained using Search!! are mostly random, it is possible to obtain certain items through RNG manipulation, namely the powerful washroom set. Note that by having 99+ of an item type and 99900+ bira, the RNG pattern will change and cannot be redone.

Trivia

 * The magic bus is powered by magic, and Magical Vacation rumors alleges that similar vehicles used to run on fossil fuels over ten thousand years ago. Since Latte was built around the same time, this is possibly in reference to the era of the Espresso civilization.
