Children's magazine with information, topical items and performance. Adventurer, naturalist, explorer, daredevil: call him what you want but this week, Blue Peter is guest hosted by Steve Backshall. Fresh from filming his new series, he'll be showing viewers how to make the final part of Blue Peter's Wildlife City - a hedgehog house for their hibernation! He may have travelled the globe, but Steve is transported into a whole new world via computer wizardry live in studio. There's also a chance to see the second part of Barney's Big Bike Challenge as he prepares for his 60 mile journey across the Cumbrian hills.
