I don’t really know d&d well, but I just looked up the spell and I think it says you can transform “any number of willing creatures”. So the DM could make an argument about whether insects had the intelligence to even qualify as being able to be “willing” for that.

On the other hand, I am a big fan of Operation Dumbo Drop Multistrike

I’m gonna guess the original version of this joke said “crashed” instead of “fell over”, cause then it would actually be ambiguous enough for the premise to work.
