[FEATURE] Invincible, fixed size snowballs in any season

[DullPointer]

Describe the feature you'd like
Snowballs to be fixed at their starting size and not change size when moved over snow or regular ground. Snowballs to not get destroyed when hit off of other objects. Snowballs to be spawnable in any season. If possible have ability to force spawn snowballs.

Additional context
This feature request is an attempt to crudely replicate the behavior of the kick-able balls from classic Animal Crossing for GameCube.

Thank you very much for your consideration and good luck with this project in general.
