Snowmen seem like such jolly fellows that it's hard to imagine them fighting anybody -- least of all Santa Claus. But when a snowy gent decides to try his hand at impersonating the big guy, Santa has to defend his turf. The North Pole becomes a comic battleground as Santa's mechanical creations take on the snowball fury of the easily angered Snowman. John A. Davis' animated short Santa vs. the Snowman is practically a holiday tradition at the Saint Louis Science Center. Catch it during its limited run through the end of the year.
Noon daily (Dec. 19-24, 26-31). Saint Louis Science Center OMNIMAX (5050 Oakland Avenue; 314-289-4400 or www.slsc.org). $5-$6.
