Smiley (the axolotl) is in reality a compressed gas having a DF power.

The bait it took could be another form of artificial DF, therefore in consuming two DFs, it - as Lucci mentioned - exploded and releases its compressed gas which happens to be poisonous in the first place.

Imagine you have a way to create a chemical weapon in the form of gas, able to turn it into some sort of life form using DF power, tell it to go to an area you would like to cause harm, plant the bait there (which is another DF in a different form) which seems harmless enough, get it to eat the second DF, blows up and releases the chemical weapon at that area! Enemy wiped out, mission accomplished!
