The UNDERDOG adds the total number of foreign colonies (other than their own) to their attack total BUT only for aliens that have more foreign colonies than the UNDERDOG. For example, take aliens A, B, C, U (underdog). A has 1 foreign colon...y, B has 3 foreign colonies, C has 4 foreign colonies, U has 2 foreign colonies. Hence, U could add 7 (B + C) to his/her attack total.
The SQUABBLER. If invited to ally - if both players negotiate then the SQUABBLER may use his/her power to quash the deal. If only one player negotiates and the SQUABBLER has allied with them, the SQUABBLER may use his/her power to cancel the negotiating players compensation.
