SpongeBob Tower Defense Update 14 Trade Value List and How to Trade Guide!

The latest Update 14 of SpongeBob Tower Defense finally delivers something players have been asking for since launch—trading mechanics. With this new feature, you no longer need to depend solely on RNG to get your favorite characters. Whether you’re after a specific limited unit or an ultra-rare item, now you can exchange with other players directly.

But with great trading power comes the need for value knowledge. If you’re unsure what your units or items are worth, this guide breaks down the entire value list for all tradeable characters and items in the game. Use it to make smart and fair trades every time.

How to Trade in SpongeBob Tower Defense

1. Launch the game on your platform.

2. In the main lobby, look for the Flying Dutchman NPC on the left side.

3. Interact with him to open the trade panel showing available players.

4. Choose a player and send a trade invite.

5. Once accepted, a trading window will appear where you can offer characters and items.
