Carbon datings show these carvings have been found in cave walls dating back to the 4th century BC. This proves that Doraemon has traveled in time or aliens have seen Doraemon in passed centuries.
I'm glad to share this concrete finding revealing the ingenuity of the youth of our generation. In the past we only carved our initials in cement but now kids are returning to the creative past time of Doraemon carving.
By the way my friend had a red Beetle in high school. Do you recognize this Beetle? If you do can you tell me its origins because it is preety creepy to me.
