I'd turn into a Zaleszczotek książkowy (Chelifer cancroides). It doesn't look impressive but bear with me!! This bug is really small and shy but it feeds on parasites that destroy your books (you can find a reference to this in its polish name, it's impossible to translate this but trust me, the name is really cute) and beehives, so it protects books and bees with these tiny pincers bigger than its body.
My second choice would be a fungus-growing ant. All ants and all fungis are cool and I love them very much so what more could I wish for.
