Artificial intelligence dolls and robots which cost over £100 are this year's Christmas must-have toys

This year's Christmas must-have toys will be life-like dolls with artificial intelligence and a Lego robot which can be controlled from an iPad, according to Argos.

But the introduction of new "pimped up" versions of classic toys mean parents can expect to takean extra large hit to the wallet, as the toys are part of a growing number which cost over £100.

Argos said the new breed of £100 gift could spell the end of children expecting a full Santa sack as they would be hoping for one or two high value items instead. 

It said the most popular choice among parents this year was a "blockbuster gift", with over half (54 per cent) planning on purchasing a "gasp out loud" present alongside a couple of stocking fillers. 

The Luvabella doll, which retails at £99.99, has fluid movements and responses to being fed and cared for like a real baby. For example she laughs when her feet are ticked, and gets upset when her eyes are covered for too long. 

Also aimed at girls is a "Tiny Treasures Twin Set" doll for £79.99, which is available as a set of twins. One boy, one girl, the dolls are weighted like real newborns and have sleepy eyes, silky newborn hair, super-soft skin and its skin is made to smell like a real baby.

LEGO Boost, which retails at £149.99 lets children build five different models out of bricks including Vernie the robot, all of which can be brought to life by coding through a free app which can be downloaded to an iPad.

A spokeswoman at Let Toys Be Toys, which campaigns for gender equality in toys, said: "When the price of toys is rising, people buying toys may feel their 'safe' option is to fall back on tired stereotypes of toys for girls or toys for boys. In fact, when spending a significant amount on a toy, it is even more important that children get the chance to find something they'll really love."
