As for making animations in Blender, here are a few links if one is interested:
FeralHeart Blender Tutorial This is for posing, but it's a good way to get started. Be mindful as this must be purchased via dA with points or currency through PayPal. However, there are some important links in the description to at least get started.
AquaChocobo's Blender Tutorial This is a very good tutorial from one of the favorite animators, she is the one who made the popular canine and feline animation mods! The description also holds important information for those that wish to create their own animations.
I'd also recommend you or your friend read up on Blender mechanics, or watching/reading a tutorial! This way, you can know what to do much easier.
