If I were you and had to choose between the 3 I would go for the Wizard Portal, than Cabbage Hut (if you had none, I would go for that one first) and lastly the cute Kitty Knight.
Good luck deciding!
I'm very happy with my progress. I've made my 4th Unicorn (already had 3), 1 Armored Alicorn, and can make another Armored Alicorn today.
More energy for next Monster Hunt!
And indeed, cats again in the next event.
Cat lover and collector GiselleX16 must be very very pleased with this.
Good luck to GiselleX16 and all other player going for the Hiss in Boots!
