Comments on the clue

1.	I am not sure that 'up' works as an anagrind.
2.	Since 'insignificant' is only in the dictionaries as an adjective it can't really be used to define 'pipsqueak' which is a noun.
3.	The justification of "up" is presumably that it can mean something like "excited". I think it's dodgy – it's a different kind of excited.
