The previous answer was wrong.

When first making the game they had only a 10mb memory for each cartridge.

They had to get rid of some things in the game, it so happens that they couldn't take out one Pokemon without clearing the entire memory (the first evolution of Kangaskhan) , so they changed his name to "M NOTMISSING NO" that later, " MISSINGNO"

They also wiped out his moves that he could learn, and they made it nearly impossible to find in the marsh, (1-100,000).

Also if you want to know something cool imagine cubone without his Mom's skull, it looks just like Kangas
