Robot should not be used in the same campaign as Thunder Ball (Raiju); the latter's lightning will cause Robot to malfunction (heavy penalty to campaign result). This essentially means that in growth camps Thunder Ball can grow Robot, but Robot cannot grow Thunder Ball OR other pets in Thunder Ball's presence.

Strategy

Thunder Ball is particularly noteworthy as it starts out with very high base growth without any investment outside of the pet token it costs, comparable to Vampire. This makes it a good choice for a first token pet, though if one has Vampire it is generally advised to instead token other, more useful pets until you are at the point where you can Evolve Thunder Ball.

Once evolved, Raiju's relatively high specialist bonus and innate bonus to growth campaigns makes it an excellent candidate for long term occupation of your GC.
