Here's another one from the murky depths of my imagination.
The hornet's nest. It appears in/on fruit trees.
Basically, a more dangerous version of the ant's nest.
Instead of peaceful ants, that will only attack you when you raid the nest, hornet's nest are patrolled actively. 3 hornets fly about it, like ants would around their nest, but the hornets will attack anyone who comes too close. RUN NOOBS, RUN!
Furthermore, when you opt to raid the nest, additional hornets will spawn from it to attack you.
My idea of their moves and attacks:
buzz (move)
cost: free
drains 1 IP from the player, hornet gains 2 IP, hornet gains +1 advantage
combat intensity +2
spray poison (move)
cost: 2 IP
drains all of the player's offense and defense
Bite (attack)
cost: 1 IP, needs combat intensity <5
does quite a bit more damage than an ant's attack.
should be capable of hurting a relatively high level player, at least with full advantage
combat intensity +1
Sting (attack)
cost: free, needs combat intensity >5
Does similar damage as Bite
Resets combat intensity. Hornet gains IP equal to the intensity reduced
And yes, there is a real hornet species that is able to shoot it's poison towards is foe, from the air.
Raiding the nest could yield the following curios:
hornet's nest
hornet larvae
hornet queen
