Normal Sudoku rules apply.
Shade some cells in the grid to create 9 different pentominoes with no repeats by rotation or reflection such that no pentominoes share an edge, every pentomino includes exactly one small number clue, and every 2x2 square of the grid contains at least one cell of a pentomino.
Digits in a pentomino cannot repeat and must sum to the small number clue it contains.
Digits in caged cells show the size of the orthogonally connected region of shaded or unshaded cells they belong to.
Cells joined by a black dot contain digits in a 1:2 ratio. Not all such dots are given.
For reference, these are the 12 standard pentominoes from which the 9 in this puzzle are chosen:
Solution code: Row 3 followed by column 5

Some pretty cool and fun deductions in this one! Probably a bit harder than 2 stars, but still very fun!

Very nice. Virtual cages where you can't use the calculator tool are a bit of an achilles heel for me but got there after an enjoyable 46 minute tussle with it. Thank you!

Fixed puzzle wording to include shading as part of placing pentominoes

"Digits in caged cells show the size of the orthogonally connected region of shaded or unshaded cells they belong to."
As far as I can tell, this is the first mention of shading in the instructions. Can I assume that pentominoes are shaded? Apologies if that deduction should be blatantly obvious at my humble level.

No, you're completely right, and this has been pointed out to me elsewhere too, sorry about that. I'm fixing it very soon.
Edit: fixed :)

That ... was a lot of fun. I thought it would be hopeless at first, as I stared at the grid with no clue what to do first. Then I had two major facepalm moments in a row and suddenly it became the perfect balance of fun and struggle.
