Godzilla was getting tired of feeling several racers zip around him for a race was going on and the King of the Monsters just so happen to stumble himself onto an infamous part of the Mario Kart grand prix, with Gojira firing off his atomic breath at the racers trying to enjoy their race on the main circuit themed around the castle of the main princess.
"Something tells me Goji doesn't like the pesky plumber running this." A female Mii driver said while being whacked out of her kart by Godzilla slamming his giant dinosaur tail around.
"Seems like he doesn't want to be here either." Lakitu murmured upon signalling the change of lap for he suddenly fell out of his cloud due to Godzilla roaring loudly.
Eventually Godzilla got bored and breathed his atomic pulse everywhere, toppling over the castle and continuing on his way for he was getting tired of the bland vibrant colors due to him not having rested up enough.
