Purplehelmet, actually those blocks are two 16pixel*16pixel blocks with standard height and length of a solid block. If the height was 8pixels like the thin horizontal slopes in the Craterian climb room (or old Tourian escape shaft, respectively), one could shinespark through them if the shinespark is started at an appropriate height. In the case of pre-Wave room, a Ceiling-CF. with Grapple-shot afterwards [

Otherwise one usually would need either a frozen creature at an appropriate place, a crouch-jump started on ground about 2 block-heights below 1-block-thick platforms, or one would need to simulate having ground below a platform using infinite-Grapple-jumps and extend a crouch-jump via delayed shinespark [

If you want to know about ceiling-clips in general, you might also want to read Act(E1) or parts of Act(Y) in chapter Y of version 1 of my old compendium [
