So! You have a block! It's pretty cute, huh, that little ol' block. But still... It looks like it might be... missing something.
Lucky for you, there's all sorts of things you can do with the block! You can always buy it
accessories to help make it a little more fashionable, or if you're looking for a bit more of an impression, you can buy your block a couple
catalysts for it to hang about with! And who knows; some strange things have been happening to blocks who spend a bit
too much time with their catalysts...
Here's the fun part! See the complete combination list to see if the items you like can be combined! You don't have to buy catalysts if you really like the plain old Block.
If you already have a plain Block, you can buy it catalysts at any time.

meat (25g) - for carnivorous dreams.

leaves (25g) - scrumptious and good for you!

grass (25g) - for eating or for hiding in.

milk (40g) - mmm, calcium!

fish (40g) - lots of Blocks love fresh fish.

veggies (40g) - crunchy and full of vitamins.

peanut (50g) - delicious and fattening.

branch (50g) - some Blocks eat twigs; others climb on them.

toy mouse (60g) - if you want your Block to dream of pouncing, he'll need this mouse to practice on!

collar (60g) - if your Block dreams of being your cuddly pet, he needs this collar.

stone (60g) - it's... just a rock.

snowball (70g) - give your Block dreams of the icy north.

magic (85g) - some animals just have a little something extra, and this magic is sure to unlock it.
Check the bottom of the first page for a full list of catalyst combinations.
Here's a complete list of accessories and prices. Please think things through! I cannot give a block two sets of wings, although I can layer head items as long as there aren't too many. You can also buy accessories for existing Blocks.
You don't have to buy any accessories if you don't want to.
Some accessories look better on certain types of blocks, but all accessories can be worn by any block.

angel wings (500g) - flutter, flutter.

demon wings (500g) - a slightly more sinister flutter, flutter.
