Not enough toys in possession??

[Capacitys]

Hey guys I am still trying to understand this game and have been playing for 2 months now.
I wanted to upgrade my toy and it says "Not enough toys in possession"
What in gods name does this mean?

Sir, this means you do not have enough toys in possession or on your account of said toy that you are upgrading. You can acquire the same type of toy from toy coins, in which after you get another one of the toys you already have, you can then proceed to upgrading. :3
