Yoshi Egg

I got the Pineapple in the Mysterious Hotel Delfino, but when I go back to the first floor I cannot find the egg. Can anyone tell me where it would be?

i can help From the start, head straight up to the hotel and talk to the manager to go
inside. Once you're in the hotel, go straight to the middle area. From there,
get to the back left corner of the room where a man is standing. Enter that
room, which is the men's room. Go to the last stall and look up to find water
damage in the ceiling. Somersault up there and you'll be in the tub of a room
upstairs. Go around the wall and talk to the woman, who mentions the strange
painting on the wall. Spray it and a Boo painting will appear. Jump through
the painting into the next room.

There, go to the other end of the room where the Boos are. You will see 4
closet doors, each with a portion of a Boo picture across them. Spray them
until the Boo side is exposed, then you can enter the following room. Spray
the pink Boos and jump onto them, and you'll see a square hole in the
ceiling. Somersault up through it, which happens to be a missing tile in the
floor upstairs. In the room you jumped up to, spray the bookshelf and walk
through the passage to the next room. Talk to the man if you like, then step
onto the odd-colored tile to fall into the room below. There, break a crate
and take one of the pineapples.

Now, go through the door out of this room. Go to the back end of the room and
go downstairs to the lobby. There, bring the pineapple to the Yoshi egg by
the counter and it'll hatch. Jump on Yoshi and head up the stairs to the top
floor. Yoshi can eat the Boos for Coins, so that'll help you when navigating
the halls up there. At the top floor, go to the back corner next to the
enclosed pool with a Shine above it. Go through the open door into that room.
Jump on the bed and go through the ceiling into the attic. Land up there with
Yoshi.

From where you start off, go up the path not blocked by a Boo. At the
intersection, take the path opposite the sleeping Boo. Eat the next sleeping
Boo you come across, and go around the corner it blocked. Head straight and
take the second left turn to find 2 sleeping Boos, one on each side. Eat the
one to the left and follow that path to an area with 4 Coins. Take them, then
pound on the cracked tile to fall into the pool room below. Take the Shine
and this stage is over.
