• Target 2 LIGHT Beast monsters you control and 2 cards your opponent controls; return them to the hand.
• Special Summon 1 "Yummy" monster from your hand or GY, but it cannot attack directly this turn.
• Return 1 Field Spell from your face-up field or GY to the hand, then you can place 1 "Yummy" Field Spell from your hand, face-up on your field.
