Just a quick and dirty merge bw the toad and a water spike found here: https://www.thingiverse.com/thing:1667333/files

Has NOT yet been printed, but I'd hazard a guess that it should be oriented upright for best results, with a couple column supports to hold up the lillypad the little guy is sitting on. If you throw a couple custom supports just inside the rim of the hole in his back, it probably wouldn't hurt either.

When I do get around to printing, I'll share a picture.

Yes

Custom column supports are probably best, but you could probably get away with Cura tree supports as well.

Watch that the supports inside the toad are small enough to come out of the hole.

Threw it in Tinkercad, made some holes, made it hollow, exported to meshmixer, did some cutting and merging, and here we are.
