I really like them,
they seem really playable and are so cute.
Green was something these guys needed, thanks to him you can special any other for the effect.
Trio gives them an actual purpose besides being cute and keeping your opponent busy allowing for nice control.
(I spotted 1 lil' mistake though: Scarfsaur Trio's lore states you need 3 materials the card itself reads 2 materials.)
If these guys would be released I'd get them
And again they are so cute <3
