The Bubble Blower is an Enrichment Item that aquatic creatures can interact with to improve their mood. It is a yellow box, with a side that has a greyish coloured fan design, with black surrounding it. On the other three sides, in the bottom middle, a red rectangle is found. It must be powered by redstone in order to work.
Dinosaurs interact with is by swimming through and around it, causing love heart particles to appear.
