Even I had a joyful smile from Bill picking a really nice visual theme to follow up on earlier outside clue puzzle idea from 9 days ago. The rhyming grids hav been some great GAS for my imagination these last two months. Enjoy the puzzle.

Author/Opus: This is the 49th puzzle from Bill Murphy, part of the Genuinely Approachable Sudoku (GAS) team.

Rules: Standard Sudoku rules (insert a number from 1 to 9 into each cell so that no number repeats in any row, column, or bold region). Also, the clues outside the grid indicate the sum of the first X numbers placed in the corresponding direction, where X is equal to the first number placed in that direction (e.g., if R1C1 is 3, then the three numbers in R1C1 (i.e., 3) and R2C1 and R3C1 all add up to 18.
