I think he overdid the tuppenny rice and treacle.
Hopefully there are more round here, this is the only one I have ever seen in my life. This might be because they are far smaller than I ever realised.

I would guess that the mean weight of a weasel is much less than one lb, so to eat half a lb of each, rice and treacle, it's little wonder they'd go POP. This is the first time I've considered the issue in over 40 years having last heard the nursery rhyme😬😂.
I think they are mostly carnivorous too so it probably doesn't do them much good to begin with.
I definitely know what this animal is but just for the other nostriches why don’t you say what it is.
