Well

The well is a structure found within Mad Monster Mansion in Banjo-Kazooie. Inside, multiple Whiplashes, 7 Musical Notes, a Mumbo Token and a Jiggy can be found. While not required, being transformed into Pumpkin Banjo makes obtaining them much easier as the form allows Banjo and Kazooie to sink and enter the drainpipe that leads to the pond outside.
