We have wolf spiders that get stupid big, and also orb weavers which also get stupid big, but they have crazy coloring.
I prefer for them to stay outside, though.
Oh yeah, well how do you feel about THIS?

Oh yeah, same, they're extremely important for the environment and their ecosystems, and I think they should stay there.
But who painted that spider? Bruh.
