Hey Guys and Gals,
GBU all 2.
Here's my "2nd- 2 part" post. 1st. one was about the "slippery moss".
As in the "slippery moss" post, "if" you hadn't read it yet, here is where I am in the game.
Research-1/2 way thru to Level 2.
Med.- Level 1
Farming- Level2
Construction- Level 2
Crafting- Level 2

Frogs and mosquitoes:
I got "some" of the frogs, but not so many that can't be "handled" by the kids. The mosquitoes are "worse" than the frogs.

Heron:
Besides getting rid of the frogs, as it says in a "tip opening" of the game whatelse is its "purpose"?
Or is it like the squirrels, a "non-essential" pet? That's what I have "read" in another VVOS2 forum site.

Opinion:

The frogs and heron could had been like in VV4, "constantly" being put in the "pond" by the "fern plant". Coming "out" during peeps' "gathering time" to have "their mosquito feast". Heron showing up at times to "snatch a frog-leg meal".
Frogs are "healer's helper", as they make the peeps "sick" and the healer's skill level "advances".
GBU and yours.
