{{Ruling| Q = When "Planckster Prank-Kids Rocket" is Special Summoned by the effect of "[[Instant Fusion]]", can I activate the effect of "Planckster Prank-Kids Rocket"?| A = When "Planckster Prank-Kids Rocket" is Special Summoned by the effect of "Instant Fusion", it is treated as a [[Fusion Summon]], so you can activate its effect. In that case, "Planckster Prank-Kids Rocket" loses 1000 ATK, but since it was Special Summoned by the effect of "Instant Fusion", it cannot attack.| cite = 86}}

{{Ruling| Q = I successfully Fusion Summon a "Planckster Prank-Kids Rocket" and activate its effect. What happens if my opponent chains "[[Book of Moon]]" and changes "Planckster Prank-Kids Rocket" to face-down [[Defense Position]]?| A = In this scenario, if the "Planckster Prank-Kids Rocket" whose effect was activated is in face-down Defense Position when that effect resolves, it cannot gain 1000 ATK, so the part of the effect that allows it to attack directly also cannot be applied. (Even if "Planckster Prank-Kids Rocket" is changed to face-up [[Attack Position]] by "[[Book of Taiyou]]", etc. that turn, it will not be able to attack directly with its effect.)| cite = 156}}

{{Ruling| Q = I successfully Fusion Summoned a "Planckster Prank-Kids Rocket" and activated its effect this turn. If "[[Skill Drain]]" is activated ''after'' it resolved, how is the effect applied?| A = If Skill Drain is activated after the effect of "Planckster Prank-Kids Rocket" has resolved, and its effects are negated, "Planckster Prank-Kids Rocket" will no longer lose 1000 ATK, but it will still be able to attack directly with its effect that turn.| cite = 162}}
