First of all Terry's dumb for attacking you for no reason. Then when you go to fight her its easy as hell. And then you basically get 2 Jiggies straight up (unless you still never unlocked the Bill Drill for whatever reason) and then another Jiggy for the eggs. Like why does Terry have like 1/3rd of the Jiggies in the level?
Uh, she attacked you because she claimed that you stole her eggs, in which you never did. Stupid Terry. And yeah, having two jiggies in her possession and another under the nest? She basically made jiggy collecting in Terrydactyland easy.

Fighting her was much of a threat, but when she spits pink stuff at you, she's got incredible aiming, unless you quickly change directions.
