It's a porcupine, it's a fish

It's Friday, so that means my quiet, peaceful week of house sitting is almost over.
This has been a daily occurrence.

 I am now in week 2 of marathon training, so Wednesday I went for my 4 mile run, and had the best thing ever happen to me.
I passed this little family probably 4-5 times, and each time they would all clap and cheer for me. How cute is that?? They didn't even know me!

My last time around I gave them high fives and decided I was going to the store to bring them back some ice cream. And that's what I did. BEST DAY EVER.

My sister and brother in law have a massive fish tank in their house, which is so beautiful, it should be in an aquarium.

Walking past it, I saw this interesting looking 'thing'.  I thought it was some kind of decoration in the tank, but when I looked later it was gone.
Kinda freaked me out. I then saw it in a different place and realized it must be some kind of fish? Or baby porcupine? :) I'm not sure...
Nemo is pretty cool too.

Happy weekend, my friends!

What is this 'thing'?
Ever had your own cheering squad while out on a run?
