That meerkat is Ma. She is standing in front of Pride Rock and Timon has taken a picture of her. Being Timon, from ''Timon and Pumbaa" he has a camera on him. "Timon. Is this Pride Rock?" "Yep. Right Pumbaa?" "Grubs, grubs, grubs." "He's sleeping, Timon." "Oh yeah. Anyway, this is where I defeated Scar, single handedly!" "No, you didn't." "Oh well. Minor exaggeration. Say cheese, Ma!" "Cheese!"- Explanation of the cheesy smile.
Nice work! Though, I don't understand what you mean by this part: "Being Timon, from ''Timon and Pumbaa" he has a camera on him.", also because Ma is from TLK 3. But nevertheless, this is great and I think this part of your idea for this was hilarious:
Timon: "Oh yeah. Anyway, this is where I defeated Scar, single handedly!" Ma: "No, you didn't." Timon: "Oh well. Minor exaggeration. Say cheese, Ma!"
I can definitely see Him trying to impress his mother, in this case. ; )
