Look for ''[VASEBREAKER_INTRO_LEVEL_NAME_3]"

Below it you should see: "FirstRewardType..powerupgadget..FirstRewardParam.&powerupgadget_powerupvasebreakerreveal"

Change "powerupgadget" to "unlock_plant" and "powerupgadget_powerupvasebreakerreveal" to "ghostpepper" (nullify the remaining for both).

Then complete Boss Vase and you'll earn ghost pepper and you'll still get the reveal vase powerup. (this only works if it's the first time you complete Boss Vase)
