Beatrice has light brown skin and black hair while sporting a blue hat and coat. Her most prominent feature is her large nose that resembles a bird's beak, hence her last name. However, an earlier design had her with lighter skin, red hair, and red pirate attire.

Beatrice Le Beak made her first physical appearance in the series in the episode "Jake and Sneaky Le Beak!", where she now has black hair and wears blue pirate attire. Beatrice Le Beak's pet falcon Fast Claw swoops down and swipes Captain Hook's hat off his head. He was quickly recognized by Mr. Smee as Le Beak's pet knowing that Beatrice Le Beak couldn't be far behind. Beatrice then appears by rowboat claiming her ship was wrecked. Captain Hook grants Beatrice permission to come aboard when she overhears Hook and his crew are going on a treasure hunt for the Splendor Gem.

Refusing to allow Le Beak to beat him to the treasure Hook gave chase and confronts Beatrice behind the falls. As the two greedy pirates battle for control of the Splendor Gem, they fall through the entrance behind the falls but are rescued by Izzy and her pixie dust, losing the Splendor Gem to the Never Sea.

Beatrice returns in the episode "Pirate Pals" much to the surprise of Captain Hook and Smee when they payed Red Jessica a visit on Crimson Isle. They try to warn Red Jessica about Le Beak's sneaky reputation, but Red Jessica doesn't believe them. But she'd soon wish she had when Beatrice cast Red Jessica and her kitten Rosie out of Crimson Castle as she makes off with Red Jessica's art collection, but she is thwarted by Red Jessica and the combined forces of Hook and Jake's crew. Seeing that she was outnumbered, Le Beak and Fast Claw decide to escape with Red Jessica's treasured art collection and ship, the Rose, with the other pirates in pursuit with Bucky and the Jolly Roger.

Originally the young pirate believed the thief was Captain Hook and his scurvy band but none of the various clues the pirates discover on Pirate Island match Hook and his crew. Jake and his crew continue searching for clues for answers. It wasn't until they discover a brown feather and ask the Sing-Songbird to identify the feather, that Sing-Songbird knew feather belong to Fast Claw, who belongs to Beatrice Le Beak. Captain Hook overheard and offered his assistance to help the puny pirate team reclaim their treasure chest, but this was merely a rues so he could snatch up the treasure for himself. Jake and his crew constructed a fake treasure chest on Pirate Island beach and hid among the foliage with Hook and Mr. Smee waiting for Le Beak's greed to be her undoing.

Beatrice Le Beak reappears in the episode "The Sneaky Snook-Off", After overhearing Captain Hook declare himself the sneakiest snook in Never Land, Le Beak soon challenges Hook to a Sneaky Snook-Off to determine who the true sneak is. Le Beak gains a huge advantage in the first challenge, a race to the top of Belch Mountain still using the whirly-hook she stole from Hook to gain victory. As Beatrice gloats over her victory a frog emerges from the brush scaring Le Beak, giving Captain Hook the advantage in the second contest crossing through Frog Hollow first. Le Beak again took the lead distracting Hook by mentioning treasure, but soon finds herself losing her cool once she encounters a large number of frogs giving Hook the victory. Beatrice was furious at Hook's dirty trick as he mocks Le Beak's fear of frogs. Beatrice soon learns the perfect revenge thanks to Mr. Smee accidentally revealing Hook's fear of Tick-Tock the Crocodile. The third challenge takes place in Crocodile Cavern, the lair of Tick-Tock Croc, and the challenge is won by the snook who strikes the gargoyle gong first.
Le Beak manages to reach the cavern first and as she begins crossing the rope bridge to the gong she wakes Tick-Tock from his slumber. Hook soon arrives shortly as he dreaded the croc was home. Le Beak gloats assured of her victory due to Hook's fear of the Tick-Tock croc. Captain Hook cuts the rope bridge, sending Beatrice plummeting into the water with the crocodile. Hook attempts to ring the gong from a far using one of his hooks, but Fast Claw intervenes, forcing Hook and Smee to cross the pit with Tick-Tock distracted attempting to devour Le Beak. But as Hook and Smee attempt to pass them, Le Beak leaps on Hook's shoulders, leaving all three pirates at the mercy of the hungry crocodile. Fortunately, Izzy manages to rescue them all using her pixie dust. With everyone safe, Le Beak and Hook still desired to ring the gong, but Skully manages to strike the gong first, ending the Sneaky Snook-Off.
