Summary
Highlights
Baby Shark introduces Lannie, his new pup friend. Lannie, a lantern shark, demonstrates her ability to glow and change colors to express emotions like anger, happiness, and hunger. She humorously comments on wearing her heart on her sleeve, despite not having sleeves.
Lannie excitedly offers Baby Shark a bed for their 'forever sleepover.' Baby Shark clarifies he already has a best friend, but Lannie remains enthusiastic about their friendship. She also mentions talking in her sleep.
Lannie is shown dreaming, imagining herself starring in an off-Broadwave production of 'Les Fish-érables' as an understudy, singing a little tune.
William, Baby Shark's best friend, meets Lannie. Lannie accidentally says 'nice to eat you' before correcting herself. Lannie and Baby Shark then practice a 'secret tail-shake' that Lannie has been working on, which later expands to include William as a 'secret tail-shake times three.'
