If you’ve mastered the chaos of dice rolls in Too Many Bones, the Lab Rats expansion will supercharge your arsenal with four new characters: Slank, Gerbil, Flan, and Helix. Each brings unique stats and a set of 16 skill dice that form a communal pool, letting you swap the right creature at the right moment and tweak your gear to the mission at hand. The goal is to create a flow where character choice and dice customization become as strategic as the attacks themselves. The package includes 21 custom dice, nine chips (one for each intern and five 3‑HP chips), a closable dice holder, and four neoprene character mats stitched along the edges. Plus, the expansion keeps the cooperative spirit of the base game while adding a layer of hand‑management that demands extra attention to decide which dice to use and when. If you enjoy experimenting with new character combos and want to explore strategic variations, Lab Rats is an addition that keeps the fun fresh and challenging. The pool‑building mechanic adds depth that can make each session more unpredictable and exciting, while still respecting the quick, accessible pace that Too Many Bones fans love. In short, Lab Rats offers more options, more complexity, and more fun for those who love the dice‑driven style of the series.
