TCG Rulings

 * This card's effect can be activated during either player's turn.

 * This effect cannot be activated during the Damage Step.


 * When "Green Baboon, Defender of the Forest" is destroyed, you cannot use its effect to Special Summon itself.


 * When "Green Baboon, Defender of the Forest" and another Beast-Type monster are destroyed at the same time by a card's effect, like "Lightning Vortex", you cannot use "Green Baboon, Defender of the Forest's" effect to Special Summon itself.


 * When a Beast-Type monster is destroyed, you cannot Special Summon multiple "Green Baboon, Defender of the Forest", even if you have multiple copies of "Green Baboon, Defender of the Forest" in your Hand/Graveyard.

Mentions in Other Rulings

 * Doomcaliber Knight: When multiple Effect Monster effects activate simultaneously, "Doomcaliber Knight's" effect is chained after determining the order of the Effect Monster effects (see the Advanced Rulings FAQ "Simultaneous Effects") and will negate the Effect Monster's effect that was placed last on the Chain.
 * Example 3: Player A's "Giant Rat" is destroyed in battle and sent to the Graveyard while she has "Green Baboon, Defender of the Forest" in her hand and "Doomcaliber Knight" is face-up on the field. Player A can activate "Giant Rat" and/or "Green Baboon, Defender of the Forest's" effect. If she activates both effects, she chooses the order the effects are placed onto the Chain, and "Doomcaliber Knight" will negate the effect that is placed highest on the Chain. If "Green Baboon, Defender of the Forest" is Chain Link 1 and "Giant Rat" is Chain Link 2, "Doomcaliber Knight" will negate "Giant Rat".


 * Light and Darkness Dragon: When the effect of a Spell, Trap, or effect of an Effect Monster is activated while the card is in your hand (“Green Baboon, Defender of the Forest”, etc.), the card will remain in the player’s hand when its activation is negated by “Light and Darkness Dragon”.


 * Queen of Thorns: .... If you Special Summon a monster from your hand by using a card effect ("Green Baboon, Defender of the Forest", etc.), you pay 1000 Life Points when the effect resolves.

OCG Rulings

 * The effects of "Soul Taker" do not resolve simultaneously. The last thing to resolve is treated as "your opponent gains Life Points" not "the monster is destroyed".  Because of this, if a Beast-Type monster is destroyed by "Soul Taker", then you cannot activate the effect of "Green Baboon, Defender of the Forest" because you miss the timing.


 * You cannot activate the effect of "Green Baboon, Defender of the Forest" which Special Summons itself during the Damage Step when a monster is destroyed by battle. You cannot activate the effect in chain to an effect like "Giant Rat" or "Nimble Momonga" when a Beast-Type monster is destroyed by battle.


 * When a Beast-Type monster is destroyed, you cannot Special Summon multiple "Green Baboon, Defender of the Forest", even if you have multiple copies of "Green Baboon, Defender of the Forest" in your Hand/Graveyard.
