The free-floating kanji in the last panel (seem to) read as "jijo", meaning "second daughter", but I have no real idea what Suwako is talking about with them.

It's 姿 "sugata" (figure, shape, form, appearance, state).

haha that's pretty funny, no offense

I used to be hit on the hand with a ruler whenever I wrote my characters too far apart :P

The curse of handwritten kanji...

still not as bad as kanji typed in a font that can turn more complex kanji into a near-unrecognisable blob.

....................The frog has a name?????

Well... Suwako has a name...

The shape of that frozen frog is so familiar...

Suwako got a Frog Rupee!
...It's sure to be valuable to SOMEONE... >_>
