I included a small amount of coconut milk in a fruit puree / failed snail jello once, and they ate it just fine. It isn't an allergen or a toxin, and they live in coconut husk with the coir, so in my opinion I think it's fine.
I suppose they're afraid of turning their faces red?
I can tell you what, that's the reason I don't eat beets anymore as well! I kept staining everything on accident (including splashing beet juice onto a shirt and carpet and staining both). So yeah, there can be no more beets in my house!
I am trying out GOLDEN beets, root & greens. I'll let you guys know.
In my garden, slugs ignore the passiflora seedlings/young plants but they eat the older plants bug leaves. They love cucumbers but ignore my cucumber vine (though they eat the fallen cucumber flowers) which have not yet fruited. Oh and the slugs and snails both LOVE LOVE LOVE fallen grapevine leaves that are browned, whether crunchy or wet and soft, but ignore green grape leaves!
Mine like new experiences too, like meeting new snails, going out to new gardens/walls/plants, new tank furniture, etc. When I first showered them out in thr sun as opposed to the kitchen sink, they looked pretty happy! Even though I thought they didn't like the sun.
