He'S nOt a rAt, hE's a mOnkEy!

Look at ZaC! Nobody taught him how to climb over bean bag, which are used to block him from entering "forbidden zones". Mummy only taught him how to descend from high places and he used it here. He knows he can't crawl onto the bean bag as it will collapse due to his weight. He used it to prop himself onto the single seater and descend to the other side.

After this episode, we narrowed the gap and placed the single seater to block him. As he was not tall enough to pro himself onto the single seater, he used his feet to step against the cupboard next to the seater and propped himself up. Wonder what mischief he will be up to next!
