This installment marks the debut of Giggles's design being accurate to her design from the Happy Tree Friends TV show and internet episodes from the third season onwards.
Her abilities remain the same (Special Power included this time), albeit more refined due to the game engine update. Giggles is a playable character in Happy Tree Friends Adventures Land. She retains her abilities from the past games, minus her Special Power. Giggles makes her first playable appearance in a spin-off in Happy Tree Friends Adventures Game Boy. Like the other playable characters, she has access to a unique Special Power once it is unlocked: Kiss of Death, a projectile attack where she blows a heart symbol from her kiss that can damage enemies. Giggles appears in Happy Tree Friends Adventures 6 as one of the playable characters. Giggles returns as a playable character in Happy Tree Friends Adventures 5 (along with Cuddles, Flaky, Petunia, Nutty, and Toothy). Giggles and the captured tree friends are rescued after Lemy and Allay prevail against the final battle against Bowser. With only Lemy and Allay as the kingdom's last hope and Neena and Tacho supporting them, they give chase to rescue Giggles and all the other captured tree friends. In Happy Tree Friends Origins, Giggles is held captive in Bowser's empire along with several other tree friends after Bowser unleashes the Dragon to Happy Tree Kingdom.
Giggles appears as one of the playable characters in Happy Tree Friends Adventures 4. Giggles is a fast runner like in the previous game. Giggles makes a return in Happy Tree Friends Adventures 3 alongside Cuddles, Flaky, Petunia, Nutty, and Toothy as a playable character, the second time in this fan series. In the "shoot 'em up" levels, she rides WinBee. Her main ability is her high running speed.
This is the first time in the overall Happy Tree Friends Adventures series where Giggles is a playable character. In Happy Tree Friends Adventures 2, Giggles, along with Cuddles, Flaky, Petunia, Nutty, and Toothy, sets out to rescue Princess Allay from the evil Bowser. They are also helped by Toothy and his spaceship to escape from Bowser's self-destructing spaceship. After they defeat Bowser for the final time, the tree friends rescue Giggles. Her friends Cuddles, Flaky, Petunia, and Nutty go to rescue her. The first Happy Tree Friends Adventures game was Giggles's debut appearance in this fan series.
