Bigger is usually better, but not with 'titREX, the city's Mardi Gras micro-krewe. The floats are big enough to carry an action figure or Barbie doll. Parade watchers are more likely to catch a bracelet than a bead necklace. This year's theme is "Too Little, Too Late" and the Angry Mermaid float references both the BP oil spill and Hans Christian Andersen's mermaid tale. The krewe was created by Bywater artists and the details on the float require a front row viewing position. The parade begins at 5:30 p.m. Saturday at Bacchanal (600 Poland Ave.) and snakes its way around the neighborhood to Vaughan's Lounge.
