Steam Gardener

Steam Gardeners are a variety of robots found in Steam Gardens of the Wooded Kingdom in Super Mario Odyssey. Steam Gardens are the autonomous gardeners of Steam Gardens, shaped like yellow watering cans. They serve mainly to water the flowers, but also to maintain the rest of the greenhouse.

At the game's finale, in the Moon Kingdom, a few Steam Gardeners can be found in attendance of the wedding between Bowser and Princess Peach. Like other attending members, they were brought forcefully. After beating the game, they can be found at the entrance of the Moon Kingdom near the Odyssey, close to the Crazy Cap store in Bowser's Kingdom, and in the start of Darker Side.
