Does Level 107 have a seeded penguin?

No. The opening frame is a blank 9x9 board with no seeded penguin or opening X.

Which yellow square is safe?

Use r7c6. The adjacent r7c7 is the source-visible red error and costs one heart.

The ninth successful penguin lands at r8c1 on the dark-magenta left edge, followed by the leaderboard with two hearts.

Solve the blank 9x9 penguin board by taking r2c2, r1c4, r4c3, safe yellow r7c6, r6c8, r3c5, r9c7, r8c9, and r8c1 while avoiding red r7c7.

Place the first penguin at brown r2c2.
Place the second penguin at dark-blue r1c4.
Place the third penguin at orange r4c3.
Place the fourth penguin at yellow r7c6; do not use the source's red-error r7c7.
Place the fifth penguin at green r6c8.
Place the sixth penguin at pink r3c5.
Place the seventh penguin at light-green r9c7.
Place the eighth penguin at light-blue r8c9.
Finish with the dark-magenta penguin at r8c1 and confirm the two-heart leaderboard transition.

Colors in this level:

Dark-magenta, Orange, Dark-blue, Pink, Light-blue, Brown, Green, Yellow, Light-green

Do not tap r7c7: the source turns it into a red error X and removes one heart before the correct yellow placement at r7c6.

Lock the upper brown, dark-blue, and orange cells before opening yellow r7c6.
After r6c8 and r3c5, close the lower-right and left edge with r9c7, r8c9, and r8c1.

Board notes 5 details

Layout: The blank 9x9 board stacks dark-magenta on the left, orange and dark-blue through the upper center, pink across the top-middle, light-blue on the right, and green, yellow, and light-green through the lower lanes.
Goal: Follow the nine successful coordinates r2c2, r1c4, r4c3, r7c6, r6c8, r3c5, r9c7, r8c9, and r8c1.
Opening: No penguins or X marks are seeded. The first three successful placements are brown r2c2, dark-blue r1c4, and orange r4c3.
Danger Zone: The source taps r7c7 incorrectly, leaving a red X and two hearts; the safe yellow cell is r7c6.
Mechanics: White Xs propagate after valid placements, while the red r7c7 mark is a real heart-losing error that remains visible through the two-heart completion.
