An elephant that swallowed a wicker basket - פיל שבלע כפיפה מצרית
The query is not regarding swallowing a whole basket, rather the query was where palm fronds were swallowed, and a basket was made from them; is it considered כלי גללים or not. Even when one may not know the final answer, he should mention the various sources that may answer the question and why ultimately, they don’t.
The מקשן assumed there was a wall which collapsed (since it states מי שהיה כותלו), ר"י suggested that כותלו means גבול כותלו, which רבא rejected. רבא even in the הו"א, only prohibited placing items which may cause damage near the boundary, but not in a case where it merely prevents improving a situation.
