|Send 10 Kirbys against a horde of titanic enemies!|
— Details menu
Survival Rush is a lot like The Arena in function. It pits the Kirbys against every significant Boss and Mid-Boss in the game. However, the way the battles are selected is unique to this Sub-Game. The Kirbys have a choice between one of three doors. Each door has a number on it, signifying how many Kirbys are required at minimum to enter. As such, if the Kirbys take too many losses, they may be barred from entering certain fights, and forced to end the run early. Each door has a specific list of encounters, but they are (mostly) randomly ordered.
In the lobby, the Kirbys have access to a healing ring and three Maxim Tomatoes, which they can use to replenish lost health or lost numbers if necessary. The game ends once the Kirbys are defeated, barred, or succeed in all 16 encounters.
The encounters are as follows:
At least 1 Kirby is needed to use this door:
At least 3 Kirbys are needed to use this door:
At least 5 Kirbys are needed to use this door:
