This is sort of unrelated (but interesting to me), but have you heard of univocalics?
If not, it's a form of writing where you only use a single vowel, e.g:
Meg kept the wee sheep,
The sheep's fleece resembled sleet;
Then wherever Meg went
The sheep went there next;
He went where she needed her texts,
The precedent he neglected;
The pre-teen felt deep cheer
When the sheep entered there.
Sadly, I can't find a source for more of them. I just found that one with a quick google search. It was partly what prompted the choice of poem in the first post I made
