The first one is Naturia Mosquito:
While you control another face-up "Naturia" monster(s), your opponent cannot select this card as an attack target. Your opponent takes any Battle Damage you would have taken from battles involving a face-up "Naturia" monster you control, except this card.
Naturia Mosquito has two Continuous Effects. The first one is the usual "lock" effect that other monsters like Marauding Captain have. If the only two monsters you control are two Naturia Mosquito, your opponent cannot attack either of them. The second effect redirects Battle Damage, much like the recently reviewed Amazoness Swords Woman. However, Mosquito redirects the Battle Damage involving all of your Naturia monsters except itself. This is not Effect Damage.
Next, we have Naturia Beans:
Once per turn, this card cannot be destroyed by battle. When this face-up card is selected as an attack target, inflict 500 Damage to your opponent.
Beans has a Continuous Effect that prevents it from being destroyed in battle once per turn. Like many Cards we have reviewed, flipping it face-down will "reset" the count, and Beans won't be destroyed once again in the same turn. The second effect is a Mandatory Trigger Effect activated upon Attack Declaration. If a replay is triggered, and Naturia Beans is chosen as an attack target again, then the damage will be inflicted once again.
Moving on, we have Naturia Bamboo Shoot:
If this card is Tribute Summoned by Tributing a "Naturia" monster, while this card remains face-up on the field, your opponent cannot activate Spell or Trap Cards.
Bamboo's effect is Continuous, and it starts being applied as soon as its Tribute Summon is successful.This means that the opponent cannot respond to the successful Summon (with Cards such as Torrential Tribute or Bottomless Trap Hole), but they can negate the Summon (with Cards like Solemn Warning or Horn of Heaven). You can use a face-down Naturia Monster, or a monster whose name is currently treated as a Naturia Monster (such as Phantom of Chaos). If Bamboo stops being face-up, it will lose its effect. If it has its effects negated temporarily (such as with Effect Veiler or Destiny Hero - Plasma), it will also lose its effect. Note that Bamboo prevents the activation of S/T Cards, which means that already active S/T Cards can activate their effects, as well as S/T Cards that activate their effects in the Graveyard like Geartown or Dark Coffin.
As for Spell Cards, we have Naturia Forest:
If you negate the activation of a card your opponent controls, you can add 1 Level 3 or lower "Naturia" monster from your Deck to your hand.
Forest has an Optional Trigger-like effect that cannot miss the timing. This means that no matter how high is the chain link in which you negate the activation, you can activate the effect, as long as you are outside of the Damage Step. If you negate two activations in the same chain, Forest's effect will activate twice in a new chain. Note that you must negate an activation, so Cards like Skill Drain or Starlight Road won't allow you to activate this effect.
And we also have Landoise's Luminous Moss:
Activate only if you control a face-up "Naturia" monster. The opponent's Effect Monsters cannot activate their effects this turn.
Moss sets a Condition during this turn that prevents Effect Monsters from activating their effects. This will even prevent the activation of Mandatory Effects. Of course, 99% of the time this won't matter, but in some scenarios, this is a little better than just negating the effect, such as if you are worried about missing the timing.
Finally, Naturias have a TCG exclusive monster, Naturia Pineapple:
All face-up monsters you control are treated as Plant-Type. If this card is in your Graveyard during your Standby Phase, and you control no Spell or Trap Cards, you can Special Summon this card. This effect cannot be activated if you control a face-up "Naturia Pineapple" or if there are any monsters in your Graveyard that are not Plant-Type or Beast-Type.
Pineapple's first effect is a Continuous Effect. If DNA Surgery is already on the Field, and Pineapple is Summoned, then all monsters are treated as Plants, but if Pineapple is on the Field, and DNA Surgery is activated, then the monsters become the type set by Surgery. The second effect is an Optional Trigger Effect with a lot of requirements. It's similar to Treeborn Frog. If you control a S/T Card when the effect resolves, then it will resolve without effect.
Well, that covers the DREV Naturia Monsters, at least Q_Q
