Jellyfish Amigurumi Pattern

This jellyfish amigurumi delivers cheerful character and tactile interest with its ruffled tentacles and rounded, squishy body. The design features two joined discs (head and underside), playful curly tentacles of two lengths, and the option to add a keychain loop. Crocheted in the round with basic increases, this project is versatile in size and well-suited for whimsical gifts or personal keepsakes. Strategic eye and tentacle placement brings out the jellyfish’s classic, friendly personality.

Pattern Important Tips

• Curly tentacles are formed with increase stitches along chains for even, bouncy spirals.
• Safety eyes sit higher than the tentacle row for an expressive, well-balanced face.
• Stuff the body firmly but not so much as to distort the disc shape during assembly.
• Spacing tentacles evenly prevents bunching and ensures a uniform appearance.

Special Notes

• Use a soft, loosely spun plush or velvet yarn for maximum squish and texture.
• If gifting to a young child, consider securely embroidering eyes for safety.
• Precise placement of the tentacles and eyes will keep your jellyfish looking symmetrical and neat.
• Keychain loop is completely optional and can be omitted for a display plush.
