Coming to you live from Eger, Hungary, where the World Sudoku Championship concluded just yesterday! I finished 29th overall (25th official) and first among Dutch participants, all new personal bests!

Today's GAPP is a Tapa (Touch)!

Rules: Shade some cells so that all shaded cells form one orthogonally connected area and no 2x2 region is entirely shaded. Clues cannot be shaded, and represent the lengths of the blocks of consecutive shaded cells in the (up to) eight cells surrounding the clue. All 2x2 areas containing a checkerboard pattern of shaded cells are marked with a circle.

⚠️ Note that a negative constraint applies! ⚠️

Minor error: The example solution image contains an extra dot in the bottom right which is not supposed to be there, please ignore it.

Acquire a Speedy Sloth 🦥 by solving in 2:30 or less!
Obtain a Quick Crab 🦀 by solving in 5:00 or less!
All solvers who complete the puzzle will be rewarded with a Proud Puffin 🐦!
