Just when you thought it was safe to take your Minecraft-obsessed kids into the Lego aisle at Toys R Us … well, it is no longer safe. Leaked images of two new Minecraft Lego sets have hit fan sites, and it seems these are just the standard bearers for a larger onslaught.

Unlike the previous limited run Minecraft sets, which feature small sections of blocky landscape and teeny creepers and zombies, the two new sets The Cave and The Farm are scaled around normal-sized minifigure models – like most of the major Lego series.

Rumours of the sets have been around for a while, but news site Brick Fan got some official-looking photos online on Friday. The story also links to descriptions of the two sets on the Hamleys website.

The Cave is a mining scene complete with treasure chest, giant spider, zombie and a “Steve” minifigure. The Farm features Steve and a skeleton, plus a sheep, cow and Jack-o-lantern (which looks like it may be the right size to replace Steve’s head – an authentic touch). The sets look set to retail for between £20-£25.

The open-world building game Minecraft, which has now sold over 50m copies on PC, consoles and mobile devices, has long been referred to as a digital version of the popular construction toy. In 2012 members of Lego’s Cuusoo community, designed a Minecraft set, which received so much online support, Lego launched it as a retail product – although its sale was mostly restricted to online stores and official Lego outliets.

The new sets, however, look to be much more mainstream, with a variety of minifigs and scenes. According to Brick Fan, other sets named The First Night, Creative Box, The Ender Dragon and The Mine are also on the way.

We have approached Lego for more information. Until then, start saving.
