Tubbo took a soft breath before letting it out, opening his eyes as he held a hand out and pressed it onto the button in front of him. Nothing was loaded into his cannon except arrows, and when he saw the arrows being fired, he grinned softly as he let out a soft sigh. "Good..." He then depressed the button, checking the dispensers before replacing the arrows with TNT. He grinned as he let out a soft laugh, aggressively pressing the button again as the TNT slammed into a wall he had built. This was stress relief for him.
