Special Summon 3 "Hippo Tokens" (Beast-Type/EARTH/Level 1/ATK 0/DEF 0), but they cannot be Tributed. You cannot Special Summon monsters from the Extra Deck while a "Hippo Token" is in a Monster Zone. For the rest of this turn after this card resolves, monsters your opponent controls cannot target monsters for attacks, except "Hippo Tokens".
