I will describe three different types of transporters in animal forms:

T1 = slowest and less storage - much alike Galapagos Tortoises
T2 = fastest and modest storage - undoubtedly the Cheetahs
T3 = normal and largest storage - nonetheless the biggest land animal, Elephants!

Btw, thanks for the new T2 and T3 transporters, @nextcolony :) Upvoted and resteemed!
