Logo: We open to see a watermelon with a pink, stylized baby-like face with black eyes, red cheek blushes and purple, TV-like antennae on top of of its head sleeping until a ladybug quickly flies from the left side of the screen to the right, causing the watermelon to wake up in surprise and look at the ladybug as it flies in the opposite direction. The watermelon then happily turns around to face the ladybug until it turns to face the camera, this while colorful, stylized letters that spell out "CocoMelon" roll in from the right side of the screen to the center. The letters then quickly spin one one-by-one with the watermelon watching the movement until the same ladybug from before flies in and lands on the watermelon while the letters bounce around, and the watermelon smiles in response.

Variants:
 * On new uploads made after Moonbug Entertainment bought the channel in 2021, the camera zooms out a bit at the end and, under Cocomelon's logo, a byline showing a white stylized "M" in a navy circle appears, and navy letters forming the name "moonbug" slide out of the circle. This variant was first used on Beach Day Song | CoComelon Nursery Rhymes & Kids Songs.
 * On Christmas-themed uploads, the watermelon is on some snow and the background is blue with active snowfall. Green strands of red and green holiday lights are also hung in the top corners of the screen.

FX/SFX: CGI animation.

Music/Sounds: A fly buzzing sound, a light-hearted kiddy theme, a young child shouting "Cocomelon!" as the letters spin and a squeaky toy sound at the end.

Music/Sounds Variant: The holiday variant's music is given a Christmas-styled rendition.

Availability: Current and common. Used at the beginning of every one of their new uploads starting with Down by the Bay | CoComelon Nursery Rhymes & Kids Songs.
