Micro Mascots are bootleg MicroPets from an unknown company. They appear to have been sold in places in Europe, such as Germany, Switzerland, and the U.K.
Not much is known about what they can do. Information from the homepage of micromascot.com and the box the toys come with, state they can interact with each other, let you know how they feel, sing, eat, move around, sleep, and respond when given commands.
The Micro Mascots website is not confirmed to be official, and was run by www.switzerlandmarket.ch. If you ordered a Micro Mascot from the site, you could receive a Micro Mascot in a white cardboard box, with the name and an image of the toy your ordered, pictured on the box, near a barcode, as opposed to the packaging they usually come with.
Only a photo of Duke from eBay, with this type of box, seems to have been documented. The box calls him "Wuffy".
The official website lists these Micro Mascots figures, and stated that Baba, a sheep Micro Mascot, was yet to be released.
An alternate version of the Micro Mascots series exists, featuring two other types of animals which are not included in the Micro Mascots series: an owl and a duck. Instead of including a dog Micro Mascot called "Duke", they gave this name to the owl Micro Mascot. The name of the duck one is unknown. While they are undoubtedly from the same people, it's unknown if this series and the Micro Mascots series had different distributors or the same one.
They can come in a blue container with their names on the front, or in a cardboard box with a handle ontop.
The series is only known to consist of:
I don't know if they kept the names for Tuxedo, Rex, and Echo the same, in this series.
