Here is an idea that was around like a day ago. It's where in like 26 different far-away areas in Alphaland, there are a sub-species of Alphablocks, called "Uppercase Alphablocks", who look like amplified, and much older versions of the normal Alphablocks, and have capital letters in their tanks. The normal Alphablocks do have the ability to change their lowercase letters in their tanks into capital letters, and in "Book", you get a normal Alphablock when any capital is switched from another letter. I have the theory that there are only one of each Uppercase Alphablock, and their normal counterparts are the ones who have the power to make copies of themselves and make words. The Uppercase Alphablocks' appearances used to be normal Alphablocks who went to the Uppercase Well far away in an unknown area in Alphaland, and the well gave these Alphablocks age, and sent each of them to their own land, where they began moulting into their Uppercase forms. The Uppercase Alphablocks remained as a mystery until the Alphablocks themselves went on a big adventure to meet them in each of the 26 lands, and they get to learn more about their letter. The Uppercase Alphablocks are also known to be more intelligent than the normal ones, and some of them are also heavily modified, such as R losing an arm and both legs in the form of a hook and peg legs, S's body now having air holes on both sides and on her shoes, and has "air hair", as well as J evolving to become an actual Jaybird. Their voices are also much older than their normal counterparts. The Uppercase Alphablocks initially refuse to leave their lands, since they have become so used them and they choose to claim them as their homes. The normal Alphablocks would sometimes come to these lands to visit, and have fun with the Uppercases.
