I'm a little stuck... Click here to teach me more about this clue!

'easy to topple' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'it's very' is the wordplay.
I cannot quite understand how this works, but
'very' could be 'v' (common abbreviation) and 'v' is located in the answer.
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is located in the answer.
This explanation may well be incorrect...
