I disliked Rian Johnson since I finished watching The Last Jedi. I won't go too far into why that was (some of his ideas could have worked better if he committed to them instead of yoinking them back by the end credits), but suffice it to say that because of the 7-8-9 back and forth whiplash and the "Your Snoke Theory Sucks" Twitter snark toward the audience (yes a lot of Star Wars fans are terrible, but come on), I only saw Glass Onion because my wife really, really insisted I gave it a try.
I concede that Rian Johnson writes excellent contemporary mysteries and I enjoyed the entire run of the movie and look forward to also seeing Knives Out now. I was truly pleasantly surprised. It doesn't hurt that Daniel Craig gave a weird but impressive delivery and really sold the character he played.
An extremely cool snail eating species is the northern caiman lizard. Each easily eats 20 snails per day, they should protect your crops fairly well.
Good tip. I'll see if I can get a few of those.
