Normal sudoku rules apply.
Cells marked with grey circles contain odd digits. Cells marked with grey squares contain even digits.
The indicated 60-cell white region contains one each of the twelve standard pentominoes (no repeats by rotation or reflection).
Each pentomino encloses exactly one grey square, one grey circle, and one caged cell.
The arrangement of pentominoes must be deduced.
Once placed, the pentominoes can be shaded with just 3 colors, such that no two pentominoes of the same color touch each other orthogonally or diagonally. All pentominoes of the same color contain a digit in common that lives in the caged cell. For one group the digit is 7, the next group 8, and the last group 9.
Additionally, each pentomino behaves like a 5-cell killer cage: digits do not repeat and must sum to the value shown in the corner of the caged cell.

Thank-you Blobz for another corker! I spent 1/3 of the time placing and colouring the pentominoes, and 2/3 of the time on the sudoku. Clean and elegant from start to finish.

I struggled in the beginning because it wasn't clear for me that you are allowed to use mirrored versions of the displayed pentominos. But after that the puzzle flowed very nicely!

An interesting concept and enjoyable solve! Really liked how the different rules all came together. I think it was a 2/5 difficulty for me. Thank you for sharing!

great puzzle! was a fun solve throughout. once you get your head wrapped around the ruleset the puzzle doesn't feel particularly difficult, but I loved how cleanly the logic composed from start to finish.
