OK, a few months ago I tried to work out if a human-size gecko could climb walls, and got an answer of ‘not glass but probably other things’.

Well I did it again, and, well, I got something totally different.

So, if I got it right this time (and I actually kept my working), then Nisse could carry half a tonne with him up a glass wall before falling off. Which seems too far in the other direction.

Oh I don’t even know, who cares about realism anyway, these are pretend animal people

edit: and i misused the word ‘force’, oh well you know what i meant anyway
