Is the urine very dark or is it lighter? Aether's questions are all great too, answering those would be helpful as well.

Pedialyte is safe and a good option for syringing more water if his urine is pretty dark or to see if it helps with the smell. It's good to rule out possible problems, but to be honest, babies do have pee and poop that smell stronger than it does when they're adults, and some hedgehogs just have very stinky pee and/or poop. So it might be normal for him, and if so, he might (hopefully) grow out of it.

You could try either offering it to him in a bowl or mixing it with some water in a separate bowl - even if it's flavorless, you don't want to risk making him just refuse to drink his water at all!

Another thing you could try to get more water in him - watermelon has a lot of water, and is usually well-liked by hedgehogs. I know he's new, but if you're concerned about dehydration you could try offering him a little bit and see if he'll try it.

Also, not sure why I haven't thought of this yet, but if you can, you can also try gently pinching his skin and see how long it sticks together. If it sticks for longer than a second, he's dehydrated. Best area to try that is probably between his shoulders. May not be able to with him being new to you, but wanted to mention it!
