So,
It's kinda obvious that once the 2019 year dog *grows* next year, the 2020 one wil have that light green, and... the yellow on the 2010 PPS! That will make it the end of the line!
imagine a dog
between them
between them
So, how about starting 2021, when the 2020 dog will *grow*, change it to CATS!! Start from the yellow, just like the 2010 dog, and continue with it through the rainbow! ^-^
