This puzzle continues an exploration of hidden 2x2 geometry (the beginning of that journey can be found here), and it should be quite approachable. Thanks to henrypijames for the perfect name. Enjoy!

Rules:

Normal Sudoku, Thermometer, Arrow, and Renban rules apply (detailed explanations below).

Hidden Killers:

• Each box fully contains two hidden killer cages—one 2x2 cage that sums to 25, and one domino cage that sums to 10.
• Killer cages do not overlap.

Normal Sudoku: Place the digits 1 to 9 in every row, column, and 3x3 box.

Thermometers: Digits along thermometers strictly increase starting from the bulb end.

Arrows: Digits along arrows sum to the digit in the corresponding circle.

Renbans: Each pink line contains a set of consecutive digits in any order.

Example: Here is an example showing how the Hidden Killers might look in the completed grid.
