Hi, this is just a funny Flower Pot with the shape of a dead tree, while the plate avoids water to go all around (the pot has a hole!)
If you print the frogs with a poor fill-in, the result will be that they will float all around the pond!!!
This object was made in Tinkercad. https://www.tinkercad.com/things/1gz26r1GW2P
You can print everithing without support. Tree and plate 0.20 while frog 0.10.
