Ever since I played waluigi in MARIO party as a child I fell in love with the WAAAH. But it’s been rough. Nintendo constantly just shuts him down and never gives him the time to shine. They had another opportunity to add him to smash and they break my heart by making him as an assist trophy once again. Please Nintendo give me my waluigi. I beg you. Put him in anything other than a sports or party game. Let him fight, let him grow as character! Give the waluigi a chance! Waluigi number one!!
