Merge Master: Monster Battle [2]

What’s happening under the Bikini Bottom? All the characters are involved in some kind of battle and you are the chosen one to put the conflict to rest. Merge the letters together to unlock new units, stronger and faster than ever before. Glory awaits!
But beware! The merge arena is brutal. Enemies will be stronger and harder to beat. Only the sharpest of mind can overcome these challenges and bring peace back to the fighting sponges and starfishes. Do you have what it takes?
