Tweety and the Magic Gems, known in Japan as Tweety's Hearty Party (トゥイティーのハーティーパーティー, Tuitī no Hātī Pātī), is a party video game developed by Kotobuki System and published by Kemco in 2001 for Game Boy Advance.

Tweety wanders through the Deep Dark Woods to escape from Sylvester and finds a box.

Suddenly, the Enchanted Queen of the Deep Dark Woods, who is really Granny, finds out about this and summons Bugs Bunny, Daffy Duck, Porky Pig, Sylvester, Yosemite Sam, and Marc Antony to help her break the spell.

To do this, the Looney Tunes must travel around the world in search of the five Magic Gems to harness their powers.

"[5] IGN concluded, "While Tweety & the Magic Gems isn't the worst game in the GBA's line-up, it's definitely among the bottom of the barrel.
