Flower pot

Flower pots are five vases found near the Haunted Church of Mad Monster Mansion in Banjo-Kazooie. When Kazooie throws Blue Eggs inside of them, flowers sprout and a ghostly voice says "thank you". Once every flower pot have been filled with flowers, they reward the duo with a Jiggy.

Trivia

 * During recordings for the voice heard when flowers sprout out of the vases, Nintendo asked Grant Kirkhope to re-record the line several times, as they were insistent he was saying a swear word rather than "thank".
