Today's GAPP is a Tetropia! This puzzle was originally written for GAPP's 4 year anniversary. I ended up not using it at the time and completely forgot about it until recently, when I was going through some of my unreleased puzzles. It seems fitting to post it now, after having just featured Tetropia in our GP round!

Rules: Shade some tetrominoes (connected group of 4 shaded cells) so that no tetrominoes touch one another, not even diagonally. Each tetromino shape is used at most as many times as it appears in the shape bank given below the grid (allowing reflections and rotations). Clued cells cannot be shaded, and contain arrows indicating all of the orthogonal directions in which a shaded cell appears closest to the clued cell. At least one shaded cell must appear in the direction of an arrow.

Note that not all shapes have to be used and that ⚠️🚨 this puzzle has a negative constraint! 🚨⚠️

Acquire a Speedy Sloth 🦥 by solving in 2:30 or less!
Obtain a Quick Crab 🦀 by solving in 5:00 or less!
All solvers who complete the puzzle will be rewarded with a Discarded Dowitcher 🐦!
