At our old apartment, I have this succulent which was always being buried by the squirrels. At first I thought it may have toppled over but to be buried, now that requires some effort. Looking at the succulent, I realized, oh I see, maybe the squirrels thought they were burying a peanut coz the texture of the succulent felt like that of a peanut.
That succulent is this Haworthia reinwardtii:
Luckily the plant was resilient enough after being uprooted and buried several times
