A 90's craze is set to make a comeback in a big way thanks to a new toy egg - that hatches into a three-foot ALIEN.

The growing aliens, just like their ancestors that hit the shelves 20 years ago, come in an egg and actually 'come alive' when put in water.

Toymaker H. Grossman unveiled the small eggs at the Toy Fair 2016 in Kensington, central London.

When placed in water they burst and grow up to 36 inches long - a far cry from the original toys which did not grow at all.

Over 22 million Alien Eggs have been sold since their launch in 1999, when they shot to fame, winning Toy Craze of the Year.

The smaller eggs are priced at £0.99, with the larger models hitting the shelves at £9.99.

Martin Grossman, whose parents founded the company in 1945, said: "We've gone very heavy with the aliens again, which we've been doing since 1999 and have sold 22 million units.

"Kids love sticky, gooey, splodgy things, and they're fun and don't cost a lot of money.

"They range from handheld size, to ones which are three to four inches, to our new model which grows out of the 16-inch egg up to three foot."
