Pizza
The pizza demonstrates extraordinary morphological flexibility. It has successfully adapted to virtually every culinary tradition on Earth. Japanese pizza features mayonnaise and corn. Brazilian pizza incorporates green peas and quail eggs. Swedish pizza has been documented with banana and curry. The pizza accepts these modifications without complaint, maintaining its essential circular identity regardless of topping configuration. This adaptability extends to dietary restrictions: gluten-free crusts, vegan cheese, and cauliflower bases have all been successfully integrated into the pizza ecosystem.
Elsa
Elsa's adaptability operates within stricter canonical constraints. Her fundamental characteristics, ice powers, Scandinavian heritage, and sisterly devotion, cannot be modified without undermining the intellectual property. Disney has demonstrated limited flexibility through costume variations and seasonal merchandise, but Elsa cannot be fundamentally reimagined as a fire-wielding sovereign of the tropics without significant narrative justification. Her adaptability manifests primarily through merchandising applications: lunchboxes, bedsheets, and adhesive bandages bearing her likeness.
