The Build

[Mentat]

so the idea was to use garden mesh and some vine i've left over to create a fake tree, growing moss on it to create a kind of canopy, now i've just realised the frog may get its foot caught between the gaps and cause some damage, so maybe use something else

Foot caught in gaps on moss or on the vine made trunk? Was looking at your drawing and actually liked the idea, but with a gnarly piece of driftwood or similar for trunk.
