Blast Spinner's Cocoon Incorrectly Counts Toward Plant Objectives

Subject: Blast Spinner's cocoon incorrectly affects plant-count objectives

Game: Plants vs. Zombies 2

Bug description:

Blast Spinner's exploding cocoons appear to affect plant-related level objectives, even though the player does not plant them.

I tested the following behaviors:

1. Plant-loss objective: In Wild West Day 19, the plant-loss counter increases when a Blast Spinner cocoon explodes.
2. Plant limit: In Ancient Egypt Day 17, Blast Spinner does not create a cocoon when the lawn's plant limit is reached. After I remove a plant to create an empty space, it can create a cocoon again.
3. Plant-use objective: In levels where the player must finish using fewer than a specified number of plants, the cocoon increases the plant counter and can cause the objective to fail.

These interactions make certain objectives unnecessarily difficult or potentially impossible to complete while using Blast Spinner.

Expected behavior: Cocoons should not count as plants planted or lost by the player in plant-count objectives.

Please investigate whether this is an unintended interaction between Blast Spinner's cocoon mechanic and level objectives.
