Lethal Electric Abe:

While being Munch, go to a zap vendo, while Abe is next to him. Let Abe carry Munch with fuzzles following him and as you pass a series of enemies munch will be lethal and dangerous making abe carrying him almost invincible. But....there is a downside you have to do this in less than 5 seconds for Munch to actually fire without command. That is the part that gets really tricky. And about the fuzzles, if Abe is carrying Munch, if Munch gets hurt theylle automatically attack without command.
