Rat Race

Rat Race (こっそりラット) is the 9th Rhythm Game in Rhythm Tengoku and the 48th Rhythm Game in Rhythm Heaven Megamix. It's about the Rats trying to find cheese while running and hiding from Ms. Whiskers.

Gameplay
The three rats run across a very, very long kitchen table. During the Practice and Remixes (and in Rhythm Heaven Megamix, the first half of the game), the frontmost rat uses a stoplight to give signals. Ms. Whiskers repeatedly pops up to try to catch the rats, and when she appears, they need to stop behind a stack of plates. The music goes quiet for a few bit before it starts building up, and the rats prepare to run off.

Skill Star
The Skill Star appears on the second stop after the traffic light is thrown away.

Challenge Land
appears in the following Challenge Train courses:
 * Game Gamble: Intermediate
 * Rhythm Safari

Kossori Rat 2P
This game also appears in the 2P mode of Rhythm Tengoku (Arcade) where it is referred to as Kossori Rat 2P (こっそりラット 2P). It plays the same as the 1P version, but there are twice as many rats, with both players controlling the white rats.
