Scratch is dumb
Scratch is dumb is a trivial brainfuck substitution made by User:None1, it is made to response to the person who invented the esolang Esolang Simply Created To Annoy People Who Dislike Scratch, who wants to annoy people who dislike scratch. This esolang will tell you that Scratch IS useless and even dumb! Even dumber than brainfuck! Because Scratch has no ASCII table and no control characters (That means you cannot say mutiline text in Scratch), and not even I/O.
Introduction
This is a brainfuck-equivalent esolang, instead of brainfuck's command, you use the unprintable characters 0x00 to 0x07, that means all Scratch is dumb programs are binaries.
Why this esolang tells you that Scratch is dumb
Because this esolang uses unprintable characters which you cannot type and print in Scratch, but a proper language like brainfuck can print it easily.
Convert to brainfuck
Here is a Scratch is dumb to brainfuck table.
Scratch is dumb (hex) brainfuck 00 + 01 - 02 , 03 . 04 < 05 > 06 [ 07 ]
Example Programs
The programs here are in hex dump.
Cat Program

brainfuck Interpreter
Because dbfi is not public domain, this program is moved here.
Turing completeness
Scratch is dumb programs are binaries but it is still Turing complete because brainfuck is.
P.S.: I dislike Scratch very much, I think Scratch isn't even capable of being an esolang (nor is it capable of being a non-esoteric programming language)!
