IDK
I'm not sure how the Sprunkis would look when they go through seasons, but I'm sure Blanche would have a pair of earmuffs for winter
but what I can tell you is that Maria never changes her appearance (she is way too lazy)
Thanks. Also i took The future Blanche(5 years older and 15 years older)from The logic Of The episode "Practical Jerk" from Looney Tunes Cartoons.
