During her first playthrough of Super Mario World, Kikirara Vivi greedily collected all the coins due to her nature, triggering a trap that made the platform disappear and blocked her path. Realizing this, Vivi let out a monster-like roar 'Gao!' and went into a rampage, with the sound of her hitting the desk being called 'gunshots' by viewers. The audience dubbed her 'Vivizaurus' and 'Monster Vivi,' finding her adorable rampage both funny and healing.
