SCULPTORS: Sugar Sand FestivalMaster sculptors will once again show off their skills at the Sugar Sand Festival, running Friday through April 22 on the powdery white sand of Clearwater Beach. This year’s theme is "Sea America: A Celebration of America’s Treasures," with sculptures lined up in an exhibit in a 21,000-square-foot tent. There will also be sand-sculpting classes, a giant sandbox for kids to play in, free concerts, buskers and fireworks on Saturday at 9 p.m. You can skip Clearwater’s notorious parking problems by riding the Jolley Trolley, which will be free through April 29 with free parking at Clearwater City Hall or the Harborview Center. Festival admission is $10, $8 ages 55 and older, $6 ages 6-17, 5 and younger free at Pier 60, 10 Pier 60 Drive, Clearwater Beach. sugarsandfestival.com.IRON KIDS: Tampa Bay Kids TriathlonKids ages 6 to 14 will run, bike and swim in and around Adventure Island in the sixth annual Tampa Bay Kids Triathlon on Saturday.

He has moved on from making fun of Mel Gibson to President Trump with parodies of show tunes like How Do You Solve a Problem Like Korea? and the Roy Moore-inspired She Was 16 Going on 17. He will be singing some favorites, and there will be Q&A time with the audience, at 8 p.m. Friday. 1010 N MacInnes Place, Tampa. $39.75. (813) 229-7827. strazcenter.org.COMEDY: Katt WilliamsIn the season premiere of Atlanta, comedian Katt Williams is almost unrecognizable as Uncle Willy, an eccentric hothead who comes off as a touching version of Williams himself. But as a comic, Williams has long been arena-sized. Saturday’s show at the USF Sun Dome is his fourth booking there since 2014. Often clad in silk shirts and snakeskin boots, Williams tackles drugs, sexuality and race relations, among other polarizing topics, with his atmospheric brand of comedy. 8 p.m. Saturday. 4202 E Fowler Ave., Tampa. $49-$99. sundomearena.com.
