The legacy of Dr. Seuss continues to grow, and unlike the Grinch’s heart, it grew far beyond three sizes today.

On March 2, Dr. Seuss Enterprises will celebrate the 115th birthday of Theodor Seuss Geisel, marking the occasion with some new and expanded partnerships for fans of all ages. For those of us who were kids once and are still kids at heart, Funko is honoring the man with a Pop! Icons figure. Available from Entertainment Earth, the 3 3/4-inch vinyl figure features Dr. Seuss looking crisp in a gray suit while clutching a copy of his 1957 classic, The Cat in the Hat.

For those with the desire for a seafaring adventure, Carnival Cruise Line continues its long-running Seuss at Sea program, and on March 2 there will be a fleet-wide celebration in which all aboard will be invited to participate in a special reading of Dr. Seuss’s Happy Birthday to You! There will be themed treats, and guests may also write a personal birthday wish. Carnival will also grant 115 wishes across its 26 ships.

The first-ever Dr. Seuss mobile game arrives this spring through the newly launched Dr. Seuss Studios. Inspired by Happy Birthday to You!, B.B. the Birthday Bird takes the lead in B.B. Takes Flight. In the game, players can tap and flap through colorful lands in a Seussian world of wonder. Available for iOS and Android, the game is the first in a series of mobile games plotted for the year ahead.

Of course, you could always throw your own Dr. Seuss birthday party at home with new dress-up items and accessories from Party City.
