(This card is always treated as a "Zubaba", "Gagaga", "Gogogo", and "Dododo" card.) During your Main Phase: You can Special Summon up to 1 each "Zubaba", "Gagaga", "Gogogo", and/or "Dododo" monster(s) from your hand in Defense Position, also you cannot Special Summon from the Extra Deck for the rest of this turn, except Xyz Monsters. You can only use this effect of "Utopic Onomatopoeia" once per turn.
I remember when this card was announced without effect, everyone was thinking it was an "utopia toon" and people was "oh neos toon, stardust toon, etc" and that toon gonna be expanded to extra deck. but was not haha
