Place the first animal at r10c1 in the yellow bottom-left singleton, fixing the lower-left row and column.
Place the second animal at r4c2 in the isolated pink pocket, leaving the lower teal stair available.
Place the third animal at r2c10 in the brown upper-right singleton, locking the far-right column.
Place the fourth animal at r8c7 in the green lower-right pocket, using the open center-right column.
Place the fifth animal at r5c6 in the orange center-right lane, separating the upper blue-gray field from the lower burgundy band.
Place the sixth animal at r6c9 in the purple right-middle pocket after the green and brown edge exclusions are established.
Place the seventh animal at r3c8 in the light-green upper-right step, leaving r7c4 as the lower teal candidate.
Finish at r7c4 in the teal lower-middle stair; leave red-error r9c5 untouched and confirm the source leaderboard transition.

Colors in this level:

Blue-gray, Light-green, Brown, Pink, Orange, Purple, Teal, Green, Burgundy, Yellow

Do not tap r9c5: the source marks it red and removes one heart.
Do not confuse the red r9c5 error with the white Xs propagated from the clean-start anchors.

Use r10c1 -> r4c2 -> r2c10 -> r8c7 -> r5c6 before the r6c9 -> r3c8 -> r7c4 close.
Do not replace the successful r7c4 teal placement with red-error r9c5.

Board notes 5 details

Layout: The 10x10 opening has no seed or X mark: blue-gray covers the top and central corridor, light-green steps down the upper-right, brown is the r2c10 singleton, pink is r4c2, orange runs through the center-right, purple occupies the right-middle pockets, teal forms the lower-middle stair, green is the r8c7 pocket, burgundy dominates the lower rows, and yellow is r10c1.
Goal: Follow r10c1, r4c2, r2c10, r8c7, r5c6, r6c9, r3c8, and r7c4; the final teal placement is r7c4, not red-error r9c5.
Opening: The first decoded frame is clean. The first five successful taps are r10c1, r4c2, r2c10, r8c7, and r5c6; white Xs propagate after each legal placement.
Danger Zone: r9c5 turns into a red error X during the late teal sequence and costs one heart. Keep it excluded and finish the teal route at r7c4.
Mechanics: A long blue-gray top/corridor field meets a dense burgundy lower band; the source closes the right side in stages and transitions to the leaderboard after the eighth animal.
