Ask children to name a favorite Dr. Seuss book, and it's likely they'll toss out "One Fish Two Fish Red Fish Blue Fish" or "The Cat in the Hat" or "Green Eggs and Ham." The wacky rhymes of Theodor Seuss Geisel -- known as Dr. Seuss -- permeate American childhood. And March is the perfect time to celebrate the man, his iconic characters and his wild imagination: Friday, March 2 is Dr. Seuss' birthday, and it's also opening day for the feature film "The Lorax" based on his book of that name. This year also marks the 75th anniversary of the outlandish tale that began it all -- "And to Think That I Saw It on Mulberry Street."

Read on and see what Seussical happenings are scheduled on Long Island during March:

MARCH 2

'The Lorax' opens Rated PG

An animated version of the book of the same name features the voices of heavy hitters Zac Efron, Taylor Swift, Danny DeVito and Betty White. It tells the story of a 12-year-old boy who tries to help the girl of his dreams accomplish her longing to see a real, live tree. To find one, he must tangle with the grumpy Lorax. The movie release coincides with what would have been Dr. Seuss' 108th birthday.

In this three-part program, children in grades 2 through 6 will travel through the magical world of Dr. Seuss with the Lorax, his keeper of the trees. Begin by listening to the tale. Then, plant a tree in a Seussical pot you create. The trees will then begin adventures of their own, starting in the library's own land of the Lorax, where staff will cultivate and nurture them. Check your local library for similar programs.

Smith Haven Mall, Routes 347 and 25, Lake Grove, 1-3 p.m., 631-724-8066

COST Free

Two Dr. Seuss books will be read by local personalities, and children can take photos in front of a "Mulberry Street"-themed backdrop. The Cat in Hat will be there in costume. An episode of the PBS Kids "The Cat in the Hat Knows a Lot About That" will be shown, and children can decorate a Mulberry Street bookmark and Dr. Seuss-inspired crowns and tiaras. A parade with the kids will start and end in the center court of the mall, and at the end, kids will receive goody bags with Dr. Seuss giveaways, such as pencils and stickers. One hundred Simon Malls across the country are participating in the next month, but only Smith Haven is holding an event on Long Island.

ALL MONTH

Many school kids across Long Island will celebrate Dr. Seuss through Friday's annual Read Across America Day and some schools' annual Parents as Reading Partners programs. At Northeast Elementary School in Amityville, for instance, students will study Dr. Seuss and his works all through March in the library. The program will be launched with a reading of "And to Think I Saw It on Mulberry Street," and students will write their own silly Dr. Seuss-style stories. Silly hat day on March 30, inspired by The Cat in the Hat's topper, will cap the celebration.
