Trial Room 1 is a secret area in the sub-game Dyna Blade from Kirby Super Star and its remake. It is obtained by pressing a certain switch in Mallow Castle. It is a room filled with various Copy Essences. Enemies swarm the floor and ceiling of Trial Room 1 so that Kirby can practice using his new ability against the enemies.
- The music used here and Trial Room 2 is a remix of Mt. Dedede's lobby theme from Kirby's Dream Land.
