Spread Love With Water Gun: Quest Guide
Spray 10 guests and make sure the interaction triggers a positive reaction.

Unlock and equip the Watergun, then spray guests until 10 positive reactions register. Guests showing an angry or mad icon are the easiest targets because the water can flip their mood into the reaction the quest needs.
What to do
Research material places the Watergun in the Attractions branch after reaching a one-star park, at 1 Research Point in the documented build. Work through busy paths and watch the counter after each clear positive reaction. The same tool can clean smelly guests for a separate objective, but that is not this quest.
What the sources support
A written guide and gameplay footage agree on 10 guests and a positive response; official game material confirms that water guns are part of the game. This is stronger than relying on the quest title alone.
Version notes and limits
The target count can change in a patch. If your on-screen counter shows a different total, follow the current counter.
