Pumpkin toadlets are notably small (1.2-1.9cm from booper to pooper). At that scale, they have certain issues with their inner ears: they don't hear their own calls, and they can't land when they jump.

I've sculpted a version of a screaming toadlet that you can print at down to 2.5cm (with a LOT of attention to how you remove the supports).

The native size is closer to 10cm. I've also added the project file with three sizes (2.5cm, 5cm, and 10cm). The  pictures show 10cm, 2.5cm, and I've tossed a 1.2cm version to give a sense of scale.
