The Sing-a-ma-jigs are an American line of electronic, singing stuffed toys released by Mattel in 2010.

They are soft, plush dolls with terrycloth mouths, and measure about 12 inches in length.

A Sing-a-ma-jig's noises include songs, "jibber-jabber" made up of vowel sounds, different notes on the octave scale, a greeting, and occasionally a goodbye.

The New Yellow Sing-a-ma-jig is the only one that sung three songs in the US, Japanese, and Korean markets.

In late November 2010, the first holiday-themed Sing-a-ma-jig was introduced for Christmas and sold at Toys "R" Us stores.

The second holiday-themed doll was released in February 2011 in time for Valentine's Day.

This Sing-a-ma-jig is a white Easter rabbit with more detailed bunny ears.

The doll is red, white and blue, and sings "The Star-Spangled Banner" (the American national anthem).

Also, for the way they sign on, the pumpkin and ghost say "Trick or Treat" and the skeleton and witch say "Happy Halloween" in their tenor, bass and soprano voices.

With one press of the belly, they simultaneously open their mouths to sing, harmonize, and chatter together.

Colors include: In 2016, toy company Funrise revived the Sing-a-ma-jigs as the "Sing-a-ma-lings".
