<h3>It explains Sun's attempt to replace the Moon.</h3>
Explanation:
The poem “The Walrus and the Carpenter” that Tweedledee recites for Alice has been opens up with the Sun blazing upon the sea with all its might. The odd thing about this lines is that it was midnight and not the time for the Sun to shine.
This stanza perhaps forecasts that the poem is about forcing into someone's territory. The Sun can be seen forcing its way into Moon's way by blazing strongly in the night time.
This poem can be seen as using someone's entitlement by force or abusing someone's right.
