An Echo of Lewis Carroll in Prince Caspian?

Just re-read this passage in Prince Caspian (ch 7):

The gloomiest of all was Giant Wimbleweather. He knew it was all his fault. He sat in silence shedding big tears which collected on the end of his nose and then fell off with a huge splash on the whole bivouac of the Mice, who had just been beginning to get warm and drowsy. They all jumped up, shaking the water out of their ears and wringing their little blankets, and asked the Giant in shrill but forcible voices whether he thought they weren’t wet enough without this sort of thing. And then other people woke up and told the Mice they had been enrolled as scouts and not as a concert party, and asked why they couldn’t keep quiet. And Wimbleweather tiptoed away to find some place where he could be miserable in peace and stepped on somebody’s tail and somebody (they said afterward it was a fox) bit him. And so everyone was out of temper.

In Alice's Adventures of Wonderland, a giant Alice weeps a pool of tears, which dampens a hapless mouse:

Poor Alice! It was as much as she could do, lying down on one side, to look through into the garden with one eye; but to get through was more hopeless than ever: she sat down and began to cry again. 'You ought to be ashamed of yourself,' said Alice, 'a great girl like you,' (she might well say this), 'to go on crying in this way! Stop this moment, I tell you!' But she went on all the same, shedding gallons of tears, until there was a large pool all round her, about four inches deep and reaching half down the hall.

She then shrinks down again (by means of a fan with which she has absent-mindedly been fanning herself) and suddenly slips and then --

splash! she was up to her chin in salt water. He first idea was that she had somehow fallen into the sea, 'and in that case I can go back by railway,' she said to herself. [...] However, she soon made out that she was in the pool of tears which she had wept when she was nine feet high. 

'I wish I hadn't cried so much!' said Alice, as she swam about, trying to find her way out. 'I shall be punished for it now, I suppose, by being drowned in my own tears! That will be a queer thing, to be sure! However, everything is queer to-day.' 

Just then she heard something splashing about in the pool a little way off, and she swam nearer to make out what it was: at first she thought it must be a walrus or hippopotamus, but then she remembered how small she was now, and she soon made out that it was only a mouse that had slipped in like herself.

Alice's efforts to befriend the Mouse are not well-received.  She addresses it in French with "the first sentence in her French lesson-book" (Ou est ma chatte?) and quickly apologizes for her faux pas (I quite forgot you didn't like cats).  The Mouse expresses his indignation in "a shrill, passionate voice."

Eventually a motley assortment of bedraggled animals exit the pool, "all dripping wet, cross, and uncomfortable."
