I just got the first day of a new week, day 8something, but I don't remember getting a present yesterday for finishing the week.
I have 124 crystals, I need 145 to buy the Pegahorn. 
15 crystals...Complete 200 quests, I have 196, it's within sight
02 crystals...10 Castle upgrades.  Does the road and lamps request count as 2?  I'm on it!
03 Crystals...Buy food 10 times.  I've bought 1 but a few trips to the Fungus Hut and I can afford it.
01 crystal...Buy special consumable.  Keepsake.  Think those things cost crystals...but look!
10 crystals....35 trophys in map scenes.  I have 33. 

So completing 4 more quests and getting 2 more trophies in map scenes should give me enough crystals to buy an injured Pegahorn.  And you gals spent 69 cents   Just throwing your pennies around like there's a money tree in your backyard
 

Hey, I don't see a horn  And I tried to put the festival stuff on it and it told me a weak Pegahorn can't wear accessories

So I finally got everything timed right, my time, my experience level, etc. and did a half hour at the Hut using a double money coin.  I spent all my extra money on tiles before I started and I got up to 40,000 and I still had 40 tiles left.  So I goes shoppin'.  Captain Greg had wanted those lights and something else, where's that quest?  For some reason he's not there anymore  So I go up to the castle to see if I'd already bought that stuff.  I hadn't bought the Festival Lights yet... so where the heck did the quest disappear to  I figured I'd buy the lights, they only took some building material.   I can't quite remember the other part of it, I had thought it was a road but none of the roads stood out to me.  So I'm looking through upgrades trying to jog my memory, and I accidentally bought the Cerulean Centerpiece or something like that  When I went to look at my money I was down to 7,000  All that hard work for nothing  Well, not nothing, I got some stupid centerpiece to look at.  I can't remember what I had done before that, just that I'd given 2400,  I was going to start all these building upgrades and now I'm practically penniless.  Just when I'd gotten my new pet and was all excited.  Now I feel like quitting I'm so disgusted.

I must have bought the Yura statue that cost so much money.  That's okay, then, it was a task and it's completed now.  I finally found the quest on my list.  The only other realllly expensive thing on my list right now is orchard level 4 and that can wait for quite awhile, although IIRC it does open up some new tasks, but I've plenty to keep me going for awhile.

I don't think I got anything special for the 7th day, but I got Moonfell Soup for the start of the new week  It's like I got paid on the 8th day instead of 7t;h.
