2. The hobbits are captured, but White-Hand Uruks imposed their dominance upon the Mordor Orcs, and carried the hobbits away towards Isengard (following Saruman's orders!)
3. A single Mordor Orc, looking only to further his own advantage, carried Merry and Pippin away from the battle (in which they would have most-assuredly died, either murdered by the orcs, or trampled by the steeds of Eomer's eored)
4. Merry and Pippin, coincidentally and obliviously, in a forest measuring more than 10 000 square miles, somehow 'found' Treebeard's lap to sit upon ...
5. Merry and Pippin turned out to be creatures that were 'not on The List': without Treebeard's curiosity, he would have squashed them, or simply ignored them; they would never have spoken with him.
6. Merry and Pippin were actually in possession of information that would 'wake the Ents up', and make them think of their own peril, and investigate the danger Saruman (thereto considered a friend) perhaps, after all, presented.
7. Either Saruman, or his servants had been 'excessively reckless' in their abuse of the forest, and thereby provided the Ents with sufficient evidence to move them to declare war
The chain of absolutely-inconceivable events that bring the Ents into the war is, well, inconceivable. IIRC, Gandalf actually commented on this, after being reunited with the three hunters.
