# Add triggers

We’ll add buttons so that a user can choose which sea creature to learn about.

1. Move the play head to approximately 0:03. This will give users a small amount of time to acclimatize.
2. On the left-hand side of the timeline, select **Trigger**.
3. From the library of triggers, select **3D Button**.
4. Place the button in front of the **Transport all Players to Location** IFX, on the opposite side to the cliff wall.
5. On the timeline, select the cog on the 3D Button's container.
6. In the **End Time** field, type `00:00:30`.
7. In the **Custom Name** field, type `Clown button`.
8. In the **UI Text** field, type `Clown Fish`, and then select **Save Effect**.
9. Repeat from step 2 to create a button for the Orca Whale.
