|Soulo Shells take a simple one hit to kill. However, don't underestimate them, as their explosive nature has led to some horrible disasters, including the fall of the Treehouse in the Future. Soulo Shells can be found at the base of the chains that ground the Treehouse. Destroy them before they destroy the chains!|
- "Sector Defense" is the only mission the player is tasked to defeat these Fusions.
- These Fusions are exceptionally challenging to locate due to the small number of them in-game, oddly-timed re-spawn, and the vast quantity of players seeking them out. Due to the problems surrounding these Fusions, many players have a challenging time completing the associated Numbuh Two Nano mission, "Sector Defense."
