How do you cheer up sims on The Sims gamecube?

Answer 1

Ensure all their basic needs are met by making sure they have enough food, toilet, hygiene, sleep and interaction with other sims. Then sit them down in front of the tv or with a book for a while.

Answer 2

you can cheer another sim by playing Chess with them or giving them an instrument,,, or maybe perhaps you could cook for them with this ingredients: 1.) red snapper, 2.) chicken, 3.) eggs,, or,,, red snapper, chicken, eggs, and a honeycomb,, it should satisfy them good enough for a period of time,,......

you could eat it too,, it will add you +3 on all of your skills,, but it only works for a moment,, so you should do everything while it last,,,

Answer 3

I'm guessing by getting their needs all up. That's how it is on the second one
