The froglings are not surprised; I have given the party the initiative, but the creatures are able to react fast and move ~ though the frog targeted by Willa and Lothar has fallen out of sight behind the log.
Froglings leap onto 0707, 0807 and 0906, the last one diving into the space low, to keep under the tree. A frogling speeds down the path before leaping up into a tree above her, in 0510; the creature is about 8 feet above Valda. The last one disappears into the bush; you're not even sure which side of the path it dives into, as you're distracted by frogs leaping at you.
None of these frogs are able to attack, however, as they are somewhat slowed by their spears (they'd have time to slash with a claw, but they're holding the weapons instead).
Here's their position:
Following the party's action, the map appears as this (two froglings unaccounted for):
And the experience so far earned:
