Hedge Bird Bath is an Explorer Quest Location located on top of the Bird Bath Bluff, at the south-east corner of the Flooded Zone, by the Hedge. To reach the top of the bird bath, the simplest path involves starting at the Hedge Ascent, following the branches to the first zipline. Between the first and second zipline segments, there should be an unused anchor sitting on top of a mushroom attached to one of the branches. This anchor can be attached to a similarly-unused anchor located to the north, on an otherwise-unreachable branch. This will require three Silk Rope.
The bird bath contains the Hedgeberry SCA.B Flavor Scheme, along with a globe of Raw Science and a Mega Milk Molar.
