Flower pot

Flower Urns are five vases found near the Haunted Church of Mad Monster Mansion in Banjo-Kazooie. When Kazooie throws Blue Eggs inside of them, flowers will sprout and a ghostly voice will say "thank you". After all Flower Urns have been filled with flowers, they will 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".
